C SIM reporting
The local array generates service information messages (SIMs) to notify you of possible array service
requirements. SIMs can be generated by the array’s channel and storage path microprocessors and
service processor (SVP). The SVP reports all SIMs related to Continuous Access XP Journal processing. Each
time a SIM is generated, the amber Message LED on the array’s control panel (under the Ready and Alarm
LEDs) turns on as an additional alert.
SIMs are classified according to severity for reporting and logging purposes: service, moderate, serious,
or acute. All SIMs are recorded on the array’s SVP and displayed on Command View XP management
stations or XP Remote Web Console. You can find SIMs in the Command View XP or XP Remote Web
Console Status pane. SIMs the primary array generates include the primary data volume’s device ID (byte
13). SIMs the secondary array generates include the secondary data volume’s device ID (byte 13).
NOTE: For more information about SIM reporting, contact your HP account support representative.
If SNMP is installed and operational for the local array, each SIM results in an SNMP trap being sent to
the appropriate hosts. For more information about SNMP operations, see the HP StorageWorks Command
View XP user guide for XP Disk Arrays or the HP StorageWorks XP Remote Web Console user guide, or
contact your HP account support representative for assistance.
Figure 89 shows a typical 32-byte SIM from the local array. The six-digit reference code (RC) consists of
bytes 22, 23, and 13. The RC identifies the possible error and determines the severity. The SIM type (byte
28) indicates the component that experienced the error. When the value of byte 22 is 21, the SIM is a
control unit SIM. When the value of byte 22 is Dx (where x is an arbitrary character), the SIM is a device
SIM.
