15 SIM Reporting

TheXPstorage system reportsaserviceinformation message(SIM) to thehostwhenitisnecessary 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

valueofbyte22isDx(wherexis an arbitrarycharacter), theSIM is adeviceSIM.

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.
