HP XP P9500 Storage - Manual (Page 120)

Service information messages (SIMs)
The P9500 system generates service information messages (SIMs) when service is required. SIMs
can be generated by channel and storage path microprocessors and by .
The SVP reports all SIMs related to Continuous Access Journal processing. Each time a SIM is
generated, the amber Message LED on the control window (under the Ready and Alarm LEDs)
turns on as an additional alert for the user.
SIMs are classified into four categories according to severity for reporting and logging purposes:
service, moderate, serious, or acute.
Continuous Access Journal SIMs are displayed on Remote Web Console. You can review the SIMs
in the Status window of Remote Web Console.
•
SIMs generated by the primary system include the device ID of the P-VOL (byte 13).
•
SIMs generated by the secondary system include the device ID of the S-VOL (byte 13).
For further information on SIM reporting, contact your HP representative or HP Technical Support.
If SNMP is installed and operational for the P9500 system, each SIM results in an SNMP trap
being sent to the appropriate hosts. For further information on SNMP operations, see the HP XP
P9000 Remote Web Console User Guide, or call HP Technical Support for assistance.
The figure below shows a typical 32-byte SIM from the system. The six-digit reference code consists
of bytes 22, 23, and 13. The reference code 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.
Figure 15 Typical SIM with reference code and SIM type
The following table shows SIM reference codes, and provides useful information for identifying
issues and determining the system experiencing the problem. All SIMs are reported to the host,
except 21 80, 21 81, and possibly DC EX—depending on the value set for system option mode
598. For more information, see
“System option modes ” (page 31) .
