armrecover
Description
The armrecover reconstructs data mapping and array configuration in the
event of the loss of NVRAM contents. The data maps are reconstructed using
the latest copy of mapping information stored on the disk drives. Part of the
recovery operation includes performing a parity scan on the contents of the
entire array to validate the accuracy of the maps and to correct any drive
parity inconsistencies. This process can take up to several hours depending on
the amount of data on the array.
Caution Reducing the amount of cache memory on the array controllers
will cause a loss of the maps. Do not attempt to use the
armrecover command to restore the maps in this situation.
The maps must be rebuilt after the array is formatted.
Syntax
armrecover {-s | -p | -v <volume-set-id>} [-c] [-override] [-f] <array-id>
armrecover <array-id>
armrecover -?
Options
None Begin the recovery in interactive mode. The utility will display all
recoverable volume sets, then prompt the user for the number of the
volume sets to recover.
-c This will cause continuous polling during the recovery. The recovery is
monitored and the current progress is displayed at regular intervals.
-f Available only on firmware version HP15 and greater (VA7100/7400)
and A000 or greater (VA7410/7110), this option will perform a parity
scan at the end of the rebuild. Not specifying this option disables parity
scan.
