Minimum disk configuration for Sun StorEdge A5x00 storage arrays
This article provides a quick guide to the supported disk configuration on a Sun StorEdge A5000, A5100 and A5200 (aka photon) storage arrays.
|14||In the minimum disk drive configuration for the 14-slot disk array, disk drives are shipped in rear backplane slots 0, 3, and 6 as well as front backplane slots 3 and 6.|
|22||In the minimum disk drive configuration for the 22-slot disk array, disk drives are shipped in rear backplane slots 0, 3, 6, and 10 as well as front backplane slot 0, 5, and 10.|
Verifying minimum config when no physical access
If you are remote to your data center or do not have physical access to the Sun StorEdge array but have access to the system the array is attached then you can use the
luxadm command to verify minimum confugration.

NOTE: From the
luxadm display you can see that the array has 22 slots and contains the minimum configuration.
DO NOT MOVE DISK DRIVES FROM THE MINIMUM CONFIGURATION
