15 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 77 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(byte28)indicatesthecomponentthatexperiencedtheerror. Whenthevalueofbyte22is21,
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.

Table 58 illustrates the severity of SIMs. The table also shows SVP log files.
