Options
-a {on | off } Sets Auto Rebuild on or off. When enabled, redundancy should be
rebuilt automatically whenever a drive becomes unavailable. A value of
off indicates that rebuilds should not occur until explicitly stated.
-b { CreateLun |
FwDownload |
Security |
Select |
PassThru |
HostPort }
Break the advisory lock. For example, if the array aborts a download (or
if the download fails to complete), portions of the GUI may stop
functioning due to an advisory lock being set. If this happens you will
need to break the lock using the armmgr -b command. The advisory lock
is the result of some error condition which must be resolved before the
action can be completed without an advisory lock occurring.
-B {operating_system}
<FRULocation>
Sets the controller host port behavior for the indicated operating system.
Note that the supported operating systems vary by firmware release.
<FRULocation> identifies the host port for which the behavior is to be set.
For example, to set the behavior for host port 1 on controller 2,
enter M/C2.H1.
Note The UnsupportedOS value should only be used for a host
running an operating system that is not included in the
supported values. It is the user’s responsibility to ensure
that any unsupported host can access the array and
transfer data properly using the UnsupportedOS
behavior. HP is not responsible for any data loss that may
occur when using the UnsupportedOS behavior.
-c <FRULocation> Instructs the device to perform a reset to one of its internal fibre channel
links specified by <FRULocation>. This command is used when the array
is an unknown state.
-C {raid1+0 | hpautoraid} Sets the RAID level for the entire array. RAID 1+0 operation attempts to
store all data using RAID1+0 storage techniques. Some failure conditions
may force the data into other RAID modes temporarily.
hpautoraid - attempts to maintain the best performance while maximizing
storage efficiency. Data is moved automatically between RAID 1+0 and
RAID 5 DP.
NOTE. The RAID level can be changed from RAID 1+0 to AutoRAID on-
line. However, a full backup of all data should be done before changing
the RAID level. The RAID level cannot be changed from AutoRAID to RAID
1+0 on-line. This change requires a reformat of the entire array, which
will destroy all data. Backup all data before making this change.
