Operating Systems AIX How to increase capacity? Post 96299 by venatorm on Thursday 19th of January 2006 07:04:03 AM

For a Virtual Server (VIO) environment, I had to recreate the virtual device for the representative hdisk before I could get the additional space recognized on the AIX lpar.

AIX lpar1:
unmount fs
varyoffvg datavg
exportvg datavg
rmdev -dl hdisk1

VIO:
rmvdev the target device "rmvdev -vtd lpar1_hdisk1"
mkvdev the target device "mkvdev -vdev hdisk10 -vadapter vhost2 -dev lpar1_hdisk1"

AIX lpar1:
cfgmgr
importvg -y datavg hdisk1 (got the "appear to have grown in size" message this time)
chvg -g datavg

that is all

NAME
tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target SYNOPSIS
tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h] DESCRIPTION
Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows: iqn.2001-04.com.<hostname>-<target_name> The target name must be unique. The script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia- tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator. EXAMPLES
Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81: tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82: tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82 Create a target that uses /dev/sdb1 and allows connections from any initiator: tgt-setup-lun -d /dev/sdb1 -n my_target Display help: tgt-setup-lun -h AUTHOR
