Content Platform 9.3.6 Release notes - Customer
About this document
This document contains release notes for Hitachi Content Platform 9.3.6.
Release highlights
The HCP 9.3.6 release is a maintenance release that resolves several software issues observed in prior HCP releases, addresses several CVE vulnerabilities, and delivers hardware support for the following hardware appliance items:
- Support for Cisco N9K-C93180YC-FX3 back-end network switch
- Support for Intel Dual Port 10GigE SFP+ Ethernet X710-DA2 network adapter for HCP G10 and G11 appliance systems
Upgrade notes
Upgrades to HCP 9.3.6 will fail if any of the namespaces have HSwift protocol enabled. Disable HSwift protocol on the relevant namespaces before upgrade. Support for HSwift protocol has ended with HCP 9.3.0.
If you try to replicate namespaces with unbalanced directory mode enabled to a pre-HCP 9.3.0 version cluster, the affected tenant on the replication link will be paused. The other tenants on the replication link will continue to replicate. It is recommended to upgrade all clusters in the replication topology to HCP 9.3.0 before using the unbalanced directory mode feature.
Upgrades to version 9.2.1 or later will fail if any service plans exist that have SMTP enabled and use direct write to HCP S Series Nodes as the primary ingest tier. Please modify these service plans before upgrading to version 9.2.1 or later. For more information, please contact your authorized HCP service provider.
If you attempt to replicate objects that contain a labeled retention hold to a pre-version 9.1 cluster, the affected tenant (all its replicated namespaces) on the replication link will be paused, while other tenants on the link continue to replicate. Therefore, it is recommended to upgrade all clusters in the replication topology to Version 9.1 before using the labeled retention hold feature.
You can upgrade an HCP system to version 9.x only from version 8.x. You cannot downgrade HCP to an earlier version.
You must have at least 32 GB of RAM per node to use new software features introduced in HCP version 9.x. While you can upgrade an HCP system to version 9.x with a minimum of 12 GB of RAM per node and receive the patches and bug fixes associated with the upgrade, the system cannot use the new software features in the release. Inadequate RAM causes performance degradation and can negatively affect system stability. If you have less than 32 GB RAM per node and would like to upgrade to this release, contact your Hitachi Vantara account team.
HCP upgrades can occur with the system either online or offline. During an online upgrade, the system remains available to users and applications. Offline upgrades are faster than online upgrades, but the system is unavailable while the upgrade is in progress.

CVE Records resolved in this release
HCP 9.3.6 release resolves the following CVEs, in addition to resolving several additional security weakness not associated with these CVEs:
CVE Record Number | Hitachi Vantara reference number | Description |
CVE-2022-0778 | HCP-42996 | The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. |
CVE-2021-3711 | HCP-42996 | A bug in the implementation of the SM2 decryption code means that the calculation of the buffer size required to hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size required by the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the application a second time with a buffer that is too small. |
CVE-2021-3712 | HCP-42996 | If an application requests the printing of an ASN.1 structure that contains ASN1_STRING s that have been directly constructed by the application without NUL terminating the "data" field, a read buffer overrun can occur. |
Compatibility issues introduced in HCP 8.2 or later
The following table lists the compatibility issues introduced in HCP v8.2 or later. The issues are listed in ascending order by reference number.
Ref. number | Description | Version introduced in |
HCP-33074 HCP-35329 | In HCP v8.2, the HCP software was upgraded to Jetty v9. The upgrade introduces several security enhancements that might impact some deployments:
| HCP v8.2 |
HCP-33583 | HCP now requires that the x-amz-date header value is within 15 minutes of when HCP receives the Hitachi API for Amazon S3 request. | HCP v8.2 |
HCP-33672 | HCP now validates x-amz-date headers on appropriate Hitachi API for Amazon S3 requests. | HCP v8.2 |
HCP-35286 | HCP now sends the severity of the EventID/messages such as NOTICE, WARNING or ERROR to Syslog servers. | HCP v8.1 |
HCP-37063 | Use case of a namespace, with SMTP enabled directly writing to HCP S Series Node, is no longer supported. | HCP v8.2 |
HCP-37858 | Use case of a namespace, with SMTP enabled directly writing to HCP S Series Node, is no longer supported. | HCP v9.1 |
Known issues
The next table lists the known issues in the current release of HCP. The issues are listed in order by reference number. Where applicable, the service request number is also shown.
Reference Number | SR Number | Description |
HCP-43284 | In some circumstances, an offline upgrade might fail because the HCP shutdown process cannot unmount an encrypted archive volume. If this failure occurs, consult Hitachi VantaraSupport. An offline upgrade failure adds the following two lines to the HCP logs:
Standard ERROR for 'dmsetup remove --force archive001-crypt': device-mapper: remove ioctl on archive001-crypt failed: Device or resource busy | |
HCP-41176 | 03131048, 03141801, 03171024 | HCP running on a G11 server can raise a false-positive alert about the power supply, CPU, or disk drives. |
HCP-40505 | Manually started execution of a service is not persistent. It can be interrupted by the scheduled service or a node event such as a reboot. | |
HCP-39876 | 02673882 | In a SAN-attached HCP environment, storage addition procedure may fail, indicating that the procedure fails because of a device mapper name of mpathb (or other mpath device) cannot be formatted. |
HCP-39798 | 02639142 | Solr does not create proper indexing when user ingests a custom metadata containing format other than "Pretty formatted XML." Therefore, annotations with a single line of XML are not parsed properly when doing phrase searches. |
HCP-39465 | Objects cannot be deleted using the namespace browser when logged in as an anonymous user. Log in as an authenticated user to delete objects when using the namespace browser. | |
HCP-39045 | Space occupied by old object versions is not freed by the Garbage Collection service if the object is in a replicated namespace and the replication link is suspended. If feasible, delete the replication link or remove the namespace from replication to work around the issue. | |
HCP-38505 | HCP appears to send the correct error code, but is inconsistent with AWS in that the size check should occur earlier than it does. As a result, HCP sends a 400 error code rather than sending a 200 error code during the keep-alive procedure. | |
HCP-38408 | 02155007 | ntpd tries to bind to usb0 network interface on HCP 9.x G11 system and causes time synchronization issues. Workaround: On each node, prevent the driver from loading by denylisting in /etc/modprobe.d/aos.conf (that is, add/append the following lines in /etc/modprobe.d/aos.conf: blacklist cdc_ether blacklist usbnet |
HCP-38155 | 02090989 | Resetting advanced settings for an HCP S Series storage component does not work. |
HCP-38048 | Service clearPolicyState does not clear rows that have no matching external_file entries. | |
HCP-37935 | While troubleshooting the progress of replication, the replication link in the overview page increases when a tenant is paused. The increase in pending data is similar to the total size of the paused namespaces. | |
HCP-37851 | Starting with release HCP 8.2, all units of systemd-tmpfiles service log errors messages in /var/log/messages on a daily periodicity. The log messages are similar to the following: systemd-tmpfiles[29354]: [/usr/lib/tmpfiles.d/mdadm.conf:1] Line references path below legacy directory /var/run/, updating /var/run/mdadm → /run/mdadm; please update the tmpfiles.d/ drop-in file accordingly. Initial investigation suggests that these error messages cause no functional error symptoms in HCP. | |
HCP-37810 | When provisioning rear-cage SSD to the HCP cluster on a subset of nodes in a SAN-attached G10 or G11 configuration, the service procedure tries to add rear-cage SSD on both nodes that comprise a Zero-Copy-Failover (ZCF) pair, even if one of those nodes does not have rear-cage SSD to be provisioned. This leads to error in the service procedure. As a work-around, ensure that you provision rear-cage SSDs either for both nodes that comprise a ZCF pair, or simultaneously for all nodes in the cluster. | |
HCP-37778 | After upgrade of an HCP system is completed, the System Management Console Hardware page may display Initializing status for some of the logical volumes. This is the result of the device SMART error log containing records of error. Please contact Hitachi Vantara technical support to identify the error condition and the corrective action to resolve the symptom. | |
HCP-37754 | HCP installed in an ESXi environment may display the following FSTRIM error message on the System Management Console: "Failure encountered attempting to trim volumes on nodes:", and an error with Event ID 2818 is listed in the error log under Major Events. Please contact Hitachi Vantara customer support if you encounter this error message. | |
HCP-37753 | HCP system goes in read-only state because of node rolls due to metadata manager not starting up. System could even look unstable. Workaround: Reboot the system. | |
HCP-37696 | 01612339 | MQE shard / solr core balancing doesn’t function as desired for IPL=2 and causes incomplete query results. |
HCP-37502 | 01789465 01789463 | ATR Finalize Migration fails with "No space left on device". This is for HCP500 system with boot from SAN - they are replacing one storage system with another. In order to complete migration - arc-deploy tries to copy from LUN #0 to LUN#128. On older HCP500 system the /boot partition is only 128MB in size. |
HCP-37426 | Attempting to perform DELETE and PUTCOPY simultaneously on an object results in "Non-replicating Irreparable objects detected" error message in SMC of HCP. | |
HCP-37381 | HS3 protocol in race condition allowed both directory and file objects created with same pathname. Unlike AWS, HCP has a concept of directories. So the upper level directory cannot be also a file. | |
HCP-37342 | An unexpected duplicate row in the per-object metadata table will cause node outages until the duplicate row is removed. | |
HCP-37335 |
HCP product installation procedure may fail with the following error message if there is a USB drive or external DVD drive connected to the system when running the installation wizard: umount: /dev/sr0: umount failed: Invalid argument. This may occur in both VM and appliance configurations. Please disconnect all unnecessary USB drive and external DVD drives from the system, and retry the installation procedure, | |
HCP-37247 | HCP systems running version 8.2 and later may experience network interface flapping and resetting of network adapters. This issue may be caused by a low-level defect in the kernel that causes a network interface to stop transmitting for several seconds, which leads to the interface resetting itself and self-recovering. In active-backup network interface configurations, this leads to a network interface failover within the corresponding front-end or back-end network bond. There is no noticeable impact to clients during this very short time interval. | |
HCP-36798 | 01709881 |
SNMP returns the incorrect replication link name Workaround: Use the HCP Management API to return the correct replication link name. |
HCP-36744 | In rare circumstances, when HCP G11 operating system is installed on a node, the installation process may hang during making filesystems. This has typically been observed in SAN-attached configurations. This symptom occurs when HCP G11 detects that there appears to already be a filesystem on the volume, and the filesystem creation command is waiting for user input, but the prompt output by that command is not displayed on the console. If you are certain that the filesystem formatting procedure can continue (i.e., the volumes are mapped correctly, and all data on the volume can be destroyed), you can type in yes and press Enter, which should allow the procedure to continue. | |
HCP-36632 | 01547564 | Multipart upload fails in the FileOpenForWriteIndex.suspendAndSwap function and returns "Attempt to suspend and swap a multipart upload file handle" error |
HCP-36001 | 01410508 | Node recovery during an online upgrade procedure targets a healthy node |
HCP-35089 | 01426836 | Zero-copy failover failback might leave behind stall mount points |
HCP-35027 | 01415199 | Migration finalization might timeout and require a restart |
HCP-34993 |
01354829 01331997 | Policy state of over 1 million objects causes node reboots |
HCP-34982 |
In the HCP Search Console UI, the login ID changes to null and a subsequent search returns "500 Error: Internal server error" When you open the Tenant Management Console from the System Management Console, initiate a search by logging in to the Search Console with your system-level credentials, and either refresh the page or click the search button, the following events occur:
If you log in to the Search Console again with your tenant-level credentials and initiate a search, the query returns the following error message: 500 Error: Internal server error Workaround: Depending on the circumstances that led to this error, complete the first or both of the following steps:
| |
HCP-34764 | 01309564 | After disabling CIFS on an HCP namespace, the Windows client connection remains active, and objects are written to the root (/) file system |
HCP-34516 |
01312806 01310161 |
Overflowed, thin-provisioned block storage might cause data loss Workaround: Do not over provision dynamic pools. |
HCP-34515 | 01312806 | Major capacity of the /var file system contains log downloads |
HCP-34388 | 01224371 |
When a zero-copy-failover partner node reboots after a failover, the metadata query engine does not recover Workaround: Edit the following files:
|
HCP-34207 | Faulty SSD drives can cause a failure when adding a new SSD volume to HCP | |
HCP-34203 | Capacity calculations and UI display are inconsistent between HCP and HCP S Series Node | |
HCP-33980 | Some metadata headers are processed inconsistently between AWS S3 and HCP | |
HCP-33541 | Active/passive replication link schedule does not adjust for systems located in different time zones | |

HCP-31499 |
Inconsistent case sensitivity for Hitachi API for Amazon S3 multipart upload query parameters Case sensitivity is inconsistent among the query parameters used with S3 compatible API requests related to multipart uploads. For example, the uploadId query parameter used in requests to upload a part is not case sensitive, while the uploadId query parameter used in requests to list the parts of a multipart upload or complete or abort a multipart upload is case sensitive. | |
HCP-31488 |
System restart due to unavailable node not receiving management network IP address If a node is unavailable when the management network is enabled, the node does not receive the management network IP address. If any other change is made to the management network, the HCP system shuts down so the node can receive the management network IP address. Workaround: Only enable the management network when all nodes are available. | |
HCP-31431 |
Links in a geo-protection replication topology can be added to replication chain Geo-protection replication chains are not supported. If a system in the geo-replication topology becomes unavailable, the geo-protected systems outside of the topology could experience data unavailability | |

HCP-30958 |
DNS failover fails due to domain name change in active/passive replication link If a system is in a active/passive replication link and has its domain name changed, the replica system does not receive the updated domain name which causes DNS failover to fail. Workaround: After you change the domain name for the primary system, update any setting on the tenant overview page to replicate the new domain name. | |
HCP-30058 |
HS3 500 Internal Server Error due to double slash (//) in object name If an object has a double slash (//) in its object name and the object is ingested using HS3, HCP returns a HTTP 500 internal server error. | |

HCP-29645 |
AD falsely report missing SPNs due to replication topology with tenant or namespaces on custom network In a replication topology where systems have full SSO support, HCP may incorrectly report missing SPN errors for replicating tenants and namespaces that are using a custom network with a non-default domain name. | |
HCP-29301 | Database connections exhausted On high-load HCP systems that are balancing metadata, nodes can restart due to exceeding the database connection limit. | |
HCP-25602 |
While the Migration service is running, the migration status occasionally shows incorrect values Occasionally while the Migration service is running, the migration status values for the total number of bytes being migrated and the total number of objects being migrated are incorrect. This occurs regardless of how many bytes or objects are actually migrated. Once the migration completes, the migration status values become accurate. | |
HCP-13183 |
SNMP version 2c traps sent for version 3 traps HCP can be configured to use SNMP version 3. However, when configured this way, HCP sends version 2c traps instead of the expected version 3 traps. Workaround: To receive traps from HCP, have your SNMP application accept SNMP version 2c traps. | |
HCP-8665 |
Shredding in SAIN systems In SAIN systems, HCP may not effectively execute all three passes of the shredding algorithm when shredding objects. This is due to the fact that some storage systems make extensive use of disk caching. Depending on the particular hardware configuration and the current load on the system, some of the writes from the shredding algorithm may not make it from the cache to disk. | |
HCP-7043 |
Displaying UTF-16-encoded objects Objects with content that uses UTF-16 character encoding may not be displayed as expected due to the limitations of some browser and operating system combinations. Regardless of the appearance on the screen, the object content HCP returns is guaranteed to be identical to the data before it was stored. |
