HP StorageWorks XP Remote Web Console Software - Manual (Page 234)

Checking Service Information Messages (SIMs)
The storage system reports a service information message (SIM) to the host when it is necessary to
notify the user of a possible service requirement for the storage system. The SIMs are classified
according to severity for reporting and logging purposes: service, moderate, serious, or acute.
The SVP reports all SIMs related to Universal Replicator operations, and all SIMs are stored on the
SVP for use by HP service representatives. The SIMs reported to the host are logged in the
SYS1.LOGREC dataset of the host operating system. The Remote Web Console software displays
the SIMs to provide an additional source of notification for the user.
NOTE: For further information on SIM reporting, contact your HP service representative or HP
technical support.
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).
The following figure shows a typical 32-byte SIM from the storage system. SIMs are displayed on
the host console by reference code (RC) and severity. The six-digit RC (composed of bytes 22, 23,
and 13) identifies the possible error and determines the severity. The SIM type (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 character), the SIM is a device
SIM.
Table 54 (page 234) illustrates the severity of SIMs and explains whether or not an XP disk array
reports SIMs to the host. The table also shows the SVP log files.
