structure that has been created. If there is data on the disk array, make sure
it is backed up before performing this step.
If a LUN structure has been created on the disk array either at the factory
(A5277AZ) or by a reseller, do not perform steps 3, 4, and 5. Go to step 6 to
continue configuration of the disk array.
The disk media should be reformatted to its factory default configuration. This operation
will destroy any data on the disk array.
To initialize the disk media, type:
amutil -syswipe <ArrayID>
As the syswipe operation executes, watch the activity LEDs on the disk
Note
modules. Each LED should illuminate briefly, starting with the first disk on the
first channel, and continiung in a orderly sequence through all the disks. If the
LED on any disk remains on noticeably longer than the others, it may indicate
that the syswipe operation has encountered a problem. In this case, retry the
syswipe operation. Do not continue wth the next step until the syswipe has
completed successfully.
Step 4. Set Both Controllers to Active State
The preceding step sets controller B to the passive states. To reset both controllers to the
active state, type:
