The replacement of the server as part of a field service process can take several forms depending on how the system was originally deployed. The typical field deployment scenarios documented for service replacement include:
Two-node cluster using an external SMU for management-replacing only one node
Two-node cluster using an external SMU for management-replacing both nodes
Important This document does not treat migration scenarios between different configurations at the time of replacement.
Overview of the Hitachi NAS Platform. The Series 4000 hardware reference explains how to configure the hardware and software, and how to replace faulty components.
Consider the following server replacement requirements:
Much of the process required for a server replacement is the same as what is covered in installation and configuration training.
Determine which replacement scenario is being encountered. The replacement process is different for each scenario.
NoteReplacement servers are shipped without an embedded system management unit (SMU), so you must install the SMU before you can connect to a stand-alone server.
You can use a keyboard, video, and mouse (KVM) device or a serial cable to connect to the serial port. Bring these with you just in case they are needed when the unit arrives. If you connect to the serial port, use the following SSH client settings:
The server can be replaced onsite, however, some components are not included in your replacement server. You must remove those components from the original server and use them in the replacement server. There are a minimum of three parts to be reused in the replacement server.
The replacement server has a new MAC ID, which means that you are required to have new license keys regardless of whether you are replacing a single node or a complete cluster.
As part of the field replacement process, Hitachi Vantara recommends that you obtain temporary keys to enable quick delivery and implementation. However, any temporary keys must eventually be replaced with a permanent key. This is required for all field scenarios, except when replacing a single node in a cluster.
NoteIf the scenario is a single node or an all-cluster node replacement, use the span-allow-access command to attach the storage when the MAC ID changes.
A system backup
preserves two critical components of information:
SMU configuration
Server configuration
The backup form for
an embedded SMU is different than one from an external SMU. Depending on the
replacement scenario severity, different limitations might exist for the system
recovery.
ImportantIt is assumed that customers are frequently establishing backups somewhere safely off the platform for recovery purposes. If there is no backup, and the system to be replaced is nonfunctional, a manual recovery process is required to re-establish a functional system. The duration of this manual recovery is directly related to the complexity of the original configuration. All data and file systems are preserved independent of a backup.
Replacement servers
can be down or above a revision, and not at the expected level of firmware
required at the customer site. An upgrade is typically required during the
replacement process, which is not covered in this document. It is assumed that
all services personnel performing a replacement have already been trained, and
know where to get this information within their respective organization.
If a single server
with an embedded SMU is non-functioning, and does not have a recent backup
saved off platform, then a challenging and manual recovery process is
necessary. If this circumstance is encountered, call the support organization
for a copy of the system's latest diagnostics files. If available, these files
can be used as a guide in reestablishing the system manually. The data and file
systems will remain intact independent of the replacement and without a backup.
NoteReplacement servers are shipped without an embedded system management
unit (SMU), so you must have a SMU installed before you can connect to a
standalone server.
ImportantSet expectations up front with the customer that this will delay
time to recovery, and that some aspects of the systems configuration might
never be recovered.
If the server is online, using
NAS Manager, navigate to
HomeServer SettingsConfiguration Backup & Restore, click
backup, and then select a location to save the backup file.
Ensure you save the backup file to a safe location off platform so that you can access it after the storage system is offline.
The backup process performed by the embedded SMU will automatically capture both the SMU and server configuration files in one complete set.
Navigate to
HomeStatus & MonitoringDiagnostics download to download the diagnostic test results.
Navigate to
HomeSMU AdministrationUpgrade SMU to verify SMU type and firmware release level.
Both the server and SMU firmware versions must match those on the failed server; otherwise, the server cannot properly restore from the backup file. See the release notes and the
Hitachi NAS Platform and Hitachi Unified Storage File Module System Installation Guide for release-specific requirements.
Navigate to
HomeServer SettingsFirmware Package Management to verify the existing server (SU) firmware release level.
Navigate to
HomeServer SettingsLicense Keys to check the license keys to ensure you have the correct set of new license keys.
From the server console, issue the command:
shutdown --ship --powerdown
Wait until the console displays
Information: Server has shut down, and the rear panel LEDs turn off. The PSU and server fans continue to run until you remove the power cables from the PSU module. See the appropriate system component section for more information.
NoteThis specific
powerdown command prepares the system for both shipping, and potential long-term, post-replacement storage.
Unplug the power cords from the power supplies.
Wait approximately 15 seconds, and then confirm the NVRAM status LED is off.
If the LED is flashing or fixed, press and hold the
reset button for five seconds until the LED starts flashing. The battery disables when you release the
reset button.
Use the following rear panel figure and table to identify and label the cabling placement on the existing server.
If cables are not labeled, label them before removing them from the server.
Remove all cables from the server, and remove the server from the rack.
Remove the rail mounts from the old server, and install them on the new server.
Remove the battery from the old server, and install it in the new server.
Remove the bezel from the old server, and install it on the new server.
Insert the new server into the rack, and connect the power cords to the power supplies.
NoteDo not make any other cable connections at this time.
Obtain the necessary IP addresses to be used for the replacement server. Servers shipped from the factory have not yet had the nas-preconfig script run on them, so a replacement server will not have any IP addresses pre-configured for your use. You need IP addresses for the following:
192.0.2.200/24 eth1 (cluster IP)
192.0.2.2/24 eth1 (testhost private IP)
192.168.4.120/24 eth0 (testhost external IP, which might vary)
When you run the nas-preconfig script, it reconfigures the server to the previous settings. This step allows the SMU to recognize the server as the same and allows it to be managed. Reconfigured settings:
IP addresses for Ethernet ports 0 and 1
Gateway
Domain name
Host name
On the replacement server:
Procedure
Log in to the server.
Run the nas-preconfig script.
Reboot if you are instructed to by the script.
Log in to the SMU using one of the IP addresses you obtained.
Use a KVM (keyboard, video, and mouse) or a serial cable to connect to the serial port on the server.
Alternatively, you can connect by way of SSH using the following settings:
115,200 b/s
8 data bits
1 stop bit

Replacing a single node within a cluster assumes only two-node clusters and the presence of an external SMU, which acts as a quorum device. This helps to simplify the replacement process because a cluster preserves operational state of the entire system beyond any single node failure.
Because you are replacing an existing node from a cluster, you do not require any additional licenses, since the cluster will retain the licenses used from the existing node and the Cluster MAC-ID does not change, even if you are replacing node 1.
