display on Storage Navigator enables users to remotely view the SIMs
reported by the attached storage systems. Each time a SIM is generated,
the amber Message LED on the control panel turns on. The Hi-Track remote
maintenance tool also reports all SIMs to the support center
SIMs are classified according to severity. There are four levels: service,
moderate, serious, or acute. The service and moderate SIMs (lowest
severity) do not require immediate attention and are addressed during
routine maintenance. The serious and acute SIMs (highest severity) are
reported to the mainframe hosts once every eight hours.
The following figure illustrates a typical 32-byte SIM from the VSP storage
system. SIMs are displayed by reference code (RC) and severity. The six-
digit RC, which is composed of bytes 22, 23, and 13, identifies the possible
error and determines the severity. The SIM type, located in byte 28,
indicates which component experienced the error.
Note: If a serious or acute-level SIM is reported, call the support center
immediately to ensure that the problem is being addressed.
