HP StorageWorks XP Remote Web Console Software - Manual (Page 188)

188 Hitachi TrueCopy z/OS for HP XP12000/XP10000 and SVS 200 storage systems
also reports SIMs to the XP Command View Advanced Edition Software server or XP Remote Web Console
to provide an additional source of notification for the user.
During TC390 operations, the MCU and RCU will generate a service SIM each time the pair status of the
M-VOL or R-VOL changes for any reason, including normal status transitions (for example, pending duplex
to duplex). For TC390A transition states (suspending and deleting), a SIM is generated when the status
changes to the transition state and again when the transition is complete. SIMs generated by the MCU will
include the M-VOL device ID (byte 13) and SIMs generated by the RCU will include the R-VOL device ID
(byte 13). Use the RCU Option window (see ” Registering an RCU (Add RCU) ” on page 87) to configure
each MCU to report or not report service-level SIMs to the attached host(s).
The following figure shows a typical 32-byte SIM from the XP12000/XP10000. 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
that experienced the error. When byte 22 = 21, the SIM is a control unit SIM. When byte 22 = Dx, the SIM
is a device SIM. When byte 22 = (D5-D7, DB), the specified pair is TC390A. When byte 22 = (D8 - DC),
the pair is TC390 Synchronous. The SIM reference codes DB6x, DB7x, and DB8x indicate a TC390A pair
suspended by the RCU.

The following table lists and describes the control unit SIMs (byte 28 = F1) related to TC390 operations.
Table 49 on page 189 lists and describes the device SIMs (byte 28 = FE) related to TC390 operations.
Both of these tables also specify the severity, host reporting, and SVP log file for each SIM.
NOTE: The SIM information for the XP12000/XP10000 changes as new features and functions are
added and supported. Contact your HP account support representative or HP technical support for the
latest SIM information for the XP12000/XP10000.
