61 Error The controller reset a disk channel to recover from a communication error. This event is logged
to identify an error trend over time.

62 Warning The indicated dedicated spare disk or global spare disk has failed.
Recommended actions:
● Replace the 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.
● If the failed disk was a global spare, configure the new disk as a global spare.
● If the failed disk was a dedicated spare, configure the new disk as a dedicated spare for the
same disk group.

The controller is automatically restarted and its cache data are restored from the partner
controller’s cache.
