NAME

arrayrecover - reconstructs data mapping and array conﬁguration in the event of the loss of NVRAM con-

tents

SYNOPSIS

arrayrecover [[-s]|[-l[c]]|[-p]|[-v volume-set-id]][-c][-override][-?] array-id

DESCRIPTION

arrayrecover 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 disk

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 disk array.

The array-id used to address the disk array can be either the disk array serial number, the character dev-

ice ﬁle name of any LUN on the array (LUN 0 if no LUNs are created), or the alias text string assigned to

the disk array.

Options

arrayrecover supports the following options:

none Begin the recovery in interactive mode. The utility will display all recoverable volume

sets, then prompt for the number of the volume set to recover.

-c Used with other options, this will cause continuous polling during the recovery. The

recovery is monitored and the current progress is displayed at regular intervals.

-l Displays the array controller logs on standard output.

-lc Displays the array controller logs on standard output, and then clears the logs.

-p Begin the recovery in non-interactive mode. If there are multiple volume sets on the

disk array, a list of the volume set numbers will be displayed. If there is only one

volume set on the disk array, the recovery will be done on it. This option provides a

mechanism to pass volume set information to a script designed to perform a recovery.

-s Returns the recoverability status of the disk array, as well as the status of a recovery

in progress. The status indicates if recovery is needed, and what percentage of the

entire recovery has been completed. When used with the

-c option, status will be

returned at regular intervals allowing continuous monitoring of the recovery progress.

-v volume-set-id

Starts a recovery on the volume set indicated by volume-set-id. This option is

intended for use only in environments where there are multiple volume sets on the

disk array.

-override When speciﬁed with other options this will bypass checks on warning states and allow

a recovery command to be issued. This option should be used with caution.

-? Display expanded usage message. This option overrides all others.
