HP StorageWorks XP24000 Continuous Access Journal Software User and Reference Guide, v01 (T5278-96001, June 2007)

Checking Service I nformation Messages (SIMs)
The storage system generates SIMs (service information messages) when it i s necessary to notify the user
of possible service requirements for the storage system. SIMs can be generated by the channel and
storage path microprocessors of the storage system and by the service processor (SVP) of the storage
system. The SV
P
reports all SIMs related to Continuous Access Journal processing. Each time an SIM is
generated, the am ber Message LED on the storage system control window (under the Ready and Alarm
LEDs)
turns on as an additional aler t for the user.
SIMs are classified into four categories a c cording to severity for reporting and logging purposes: service,
moderate, ser
ious,or acute. All SIMs are recorded on the storage system SVP and displayed on Remote
Web Console c
omputers. The user can find SIMs in the Status window of Remote W eb Console. SIMs
generated by the primary storage system will include the device ID of the primary data volume (byte
13) , and SIMs generated by the secondary storage system will include the device ID of the secondary
data volume (byte 13) .
Note: For fu
rther information on SIM reporting, contact your HP service representative or HP technical
support.
If SNMP is installed and operational for the storage system, each SIM will result in an SNMP trap b eing
sent to the appropriate host(s). For further information on SNMP operations, see the HP StorageWorks
XP24000 Remote Web Console User’s Guide, or call HP technical support for assistance.
Figure 71 o
n page 1 58 shows a typical 32-byte SIM from the HP storage system. The six-digit reference
code
(RC) c
onsists of bytes 22, 23, and 1 3. The RC identifies the possible erro r and determines the
severity. The SIM t ype (byte 28) indicates the component which 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
characte
r), the SIM is a device SIM.
Table 29 on page 158 illustrates severity of SIMs. The table also shows SVP log files.
