Diagnostics — These features provide diagnostic tools. Diagnostics should be
performed by an HP service representative.
■ Array Shutdown — This setting prevents the storage array from accepting
any I/O. This will eventually cause all file system requests from the server
to fail. Data should not be lost, but applications using the storage will no
longer have access to the device.
■ Array Reset/Restart — This feature provides hard and soft resets of the
storage array. If a reset takes too long file system requests from the server
may fail. Data should not be lost, but applications using the storage will
loose access to the device until it is again ready.
■ Down A Disk — This feature logically “removes” a disk from the array
(causing it to not be used). This may cause an array RAID set rebuild.
“Downing” multiple disks could cause data to become unavailable.
The following table lists all of the features on the Command View SDM web
interface and indicates what, if any, limitations exist in conjunction with the
HP NAS 8000 solution.
