6.5 HP StoreAll OS CLI Reference Guide

ibrix_pv
Discovers, lists, and deletes physical volumes.
Description
This command discovers physical volumes that have been added to file serving nodes since the
last time the command was executed. The command excludes partitions and volumes that belong
to volume groups created for use outside of the StoreAll cluster.
Synopsis
Discover physical volumes and add them to the configuration database:
ibrix_pv -a [-h HOSTLIST] [-o FILTERDEVLIST]
The command runs on all file serving nodes or only the nodes in HOSTLIST. Omit the -o
FILTERDEVLIST option to discover all SCSI devices. To discover other types of devices, include
the -o option with the applicable keywords:
• allow_partitions: SCSI and IDE disk partitions
• ata: ATA/IDE disks
• loop: Loop devices
• mpath: LVM2 multipath
• powerpath: EMC PowerPath
The keywords for two of the multipath devices, mpath and powerpath, are mutually exclusive.
In the unlikely event that one set of hosts uses Mpath and another set uses PowerPath, an additional
run is necessary to discover all devices because the sets do not intersect:
<installdirectory>/bin/ibrix_pv -a -h HOSTLIST -o mpath
<installdirectory>/bin/ibrix_pv -a -h HOSTLIST -o powerpath
List detailed information about physical volumes:
ibrix_pv -i
For each physical volume, the output lists the following information:
# ibrix_pv -i
PV_NAME SIZE(MB) VG_NAME LUN_GROUP LV_NAME FILESYSTEM SEGNUM USED% SEGOWNER DEVICE ON SEGOWNER
------- -------- ------- --------- ------- ---------- ------ ----- -------- --------- --------
d1 3,072 ivg1 ilv1 ifs1 1 99 vm3 /dev/sdb
d2 3,072 ivg2 ilv2 ifs1 2 99 vm2 /dev/sdc

ibrix_pv -l [-h HOSTLIST]
