Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
● If you want hosts to access the volume data in the inserted disks, map the volume with a
different LUN.
76 Info. The controller is using default configuration settings. This event occurs on the first power up,
and might occur after a firmware update.
Recommended actions:
● If you have just performed a firmware update and your system requires special configuration
settings, you must make those configuration changes before your system will operate as
before.
77 Info. The cache was initialized as a result of power up or failover.
Recommended actions:
● No action is required.
78 Warning The controller could not use an assigned spare for a disk group because the spare’s capacity is
too small.
This occurs when a disk in the disk group fails, there is no dedicated spare available and all global
spares are too small or, if the dynamic spares feature is enabled, all global spares and available
disks are too small, or if there is no spare of the correct type. There may be more than one failed
disk in the system.
Recommended actions:
● Replace each failed disk with one of the same type (SSD, enterprise SAS, or midline SAS)
and the same or greater capacity. For continued optimum I/O performance, the replacement
disk should have performance that is the same as or better than the one it is replacing.
● Configure disks as dedicated spares or global spares.
○ For a dedicated spare, the disk must be of the same type as the other disks in the disk
group and at least as large as the smallest-capacity disk in the disk group, and it should
have the same or better performance.
○ For a global spare, it is best to choose a disk that is as big as or bigger than the largest
disk of its type in the system and of equal or greater performance. If the system contains
a mix of disk types (SSD, enterprise SAS, or midline SAS), there should be at least one
global spare of each type (unless dedicated spares are used to protect every disk group
of a given type).
79 Info. A trust operation has completed for the indicated disk group.
Recommended actions:
● Be sure to complete the trust procedure as documented in the CLI help for the trust
command.
80 Info. The controller enabled or disabled the indicated parameters for one or more disks.
Recommended actions:
● No action is required.
81 Info. The current controller has unkilled the partner controller. The other controller will restart.
Recommended actions:
● No action is required.
82 Info. Disk channel ID conflict.
Recommended actions:
● No action is required.
83 Info. The partner controller is changing state (shutting down or restarting).
