Actions to take when a SIM is output
When a storage system requires maintenance, a message is output. This is called a failure of a storage system (SIM: Service Information Message). SIMs are output from channels, paths, microprocessors, and so on, of the storage system. The following figure illustrates actions to take after a failure occurs.
Checking SIM reference codes
All SIMs are recorded in the storage system. When a SIM is output, Warning or Failed is displayed at the upper left of the Maintenance Utility window to notify users.
You can check SIMs on the Alert tab in the Maintenance Utility window. For details, see the System Administrator Guide.
Searching for SIM reference codes
In the SIM code lists, SIM codes that begin with the same digits are listed as a single code. For example, 602001 is shown as 602xxx (xxx indicates a pool number) in the SIM code list. Therefore, when searching for a SIM code, use the first few digits, 602 in this case, as a key word.
Handling failures
There are two types of SIMs. One can be handled by users, and the other must be handled by service personnel. For SIMs that can be handled by users, see the recovery procedures of the SIMs described in the applicable user guide to solve the problem. For the SIMs that must be handled by service personnel, contact the customer support. See SIM code list for troubleshooting by users or SIM code list for troubleshooting by service personnel for the SIM code lists.
Setting failure notification methods
SIMs can be checked on the Alert tab. In addition, they can be notified by email messages, Syslog, SNMP, or Windows Event Log. For the procedures for setting email, Syslog, and Windows Event Log notifications, see the System Administrator Guide. For the procedure for configuring the SNMP notification, see the Hitachi Alert Notification Guide.
