SSA - RAID ERRORS
1
This MAP helps you to solve problems that have occurred in SSA RAID arrays.
Attention: Unless the system unit needs to be turned off for some other reason,
do not turn off the system when servicing an SSA link or
a
unit in which SSA
devices are installed. Unit power cables and external SSA cables that connect
devices to the system can be disconnected while that system is running.
Some of the steps in this procedure ask you to change the configuration of the
array, or to change the use of an SSA disk drive. Do not do those steps unless
you have the user's permission.
Ensure that all the disk drives are
working correctly:
