SIM message types
The following SIM message types are generated by the storage unit.
Direct access storage device (DASD) SIM
Tracks DDM failures and problems.
Media SIM
Tracks data check problems on the media.
Storage unit SIM
Tracks storage unit, power control, and other hardware problems.
SIM severity levels
1 acute
An irrecoverable error with possible loss of data. This severity level only
applies to DASD SIMs.
2 serious
An irrecoverable error or a data check with loss of access to data.
3 moderate
A system path is not operational and performance might be degraded. This
severity level does not apply to media SIMs.
4 service
A recoverable error, equipment checks, or data checks. You can defer
repair.
Understanding problem status designations
Each storage unit problem creates a serviceable event. The serviceable event status
is either Open or Closed.
Problem status designations
The designations explain where the problem resides in the resolution process.
Open A problem has occurred that requires service. The status will remain in
open prior to and during the repair.
Closed
The repair was completed, and that changed the status to closed.
Managing product-specific alert traps
Product-specific alert traps provide information about problems that the storage
unit detects and that require corrective action. Either you or the service provider
must perform some action for each of these problems. The storage unit generates
the following generic, trap-6, product–specific alert traps: 1, 2, 3, 100, 101, 102, 200,
202, 210, 211, 213, 214, 215, 216, 217.
Specific information provided for trap-6, alert trap 1
Each generic, trap-6, product specific alert trap 1 provides the following
information.
Problem ID
The identifier assigned by the storage unit for the particular problem that
caused the trap.
