15 SIM Reporting
The 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 subsystem. 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 Hitachi 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 Hitachi TagmaStore USP control panel (under
the Ready and Alarm LEDs) turns on as an additional alert for the user. The XP storage system Navigator
software displays the SIMs to provide an additional source of notification for the user.
SIMs generated by the primary subsystem will include the device ID of the primary data volume (byte
13), and SIMs generated by the secondary subsystem will include the device ID of the secondary data
volume (byte 13).
Figure C.1 shows a typical 32-byte SIM from the 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.
Table C.1 illustrates severity of SIMs and explains whether or not XP Storage System reports SIMs to the
host. The table also shows SVP log files.
