C Checking Service Information Messages (SIMs)
The HP XP 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 URz operations, and all SIMs are stored on the SVP for
use by HP Data Systems personnel. The SIMs reported to the host are logged in the SYS1.LOGREC
dataset of the host operating system. Each time a SIM is generated, the amber Message LED on
the HP XP disk array control window (under the Ready and Alarm LEDs) turns on as an additional
alert for the user. The HP XP Remote Web Console software displays the SIMs to provide an
additional source of notification for the user.
NOTE: SIMs are not reported to the host by default. To report SIMs to the host, change the default
setting by using the Optional Operation window. See “Enabling or Disabling SIM Reporting”
(page 172) . For further information on SIM reporting, contact your HP 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).
“Typical SIM Showing Reference Code and SIM Type” (page 200) shows a typical 32-byte SIM
from the HP XP 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.
“Typical SIM Showing Reference Code and SIM Type” (page 200) illustrates severity of SIMs and
explains whether or not XP disk array reports SIMs to the host. The table also shows SVP log files.
