Any tips to grow iSCSI LUN

Hi,

I have an iSCSI LUN attached to an AIX 5.3 box. It's initial size is 250GB, I just grew it on the SAN to 300GB, but AIX is not seeing the change. Right now I have some processes going and it's eating up the disk space. I need to grow this lun by atleast 30GB otherwise the process with bomb and that will not be good. chvg -g <vgname> is not working. I'm thinking I need to varyoff, then varyon this disk in order to get it to work, but I can't afford that now.

If anyone has any tips and have successfully did this without take the fs offline, I would love to hear it.

ISCSI-TARGET(8) 					    BSD System Manager's Manual 					   ISCSI-TARGET(8)

NAME
iscsi-target -- service remote iSCSI requests SYNOPSIS
iscsi-target [-46DV] [-b block length] [-f configuration file] [-p port number] [-s maximum number of sessions] [-t target name] [-v verbose arg] DESCRIPTION
iscsi-target is the server for iSCSI requests from iSCSI initiators. iscsi-target listens for discovery and login requests on the required port, and responds to those requests appropriately. Options and operands available for iscsi-target: -4 iscsi-target will listen for IPv4 connections, and respond back using IPv4. This is the default address family. -6 iscsi-target will listen for IPv6 connections, and respond back using IPv6. -b blocksize Specify the underlying block size for iSCSI storage which will be served. The possible sizes are: 512, 1024, 2048, and 4096 bytes, with the default being 512 bytes. -D When this option is specified, iscsi-target will not detach itself from the controlling tty, and will not become a daemon. This can be useful for debugging purposes. -f configfile Use the named file as the configuration file. The default file can be found in /etc/iscsi/targets. See targets(5) for more informa- tion. -p port number Use the port number provided as the argument as the port on which to listen for iSCSI service requests from initiators. -s maximum number of sessions Allow the maximum number of sessions to be initiated when connecting to the target. -t filename The target name (as it appears to the iSCSI initiator) can be specified using this flag. -V iscsi-target will print the utility name and version number, and the address for bug reports, and then exit. -v argument The amount of information shown can be varied by using this command. Possible values of argument are net to show network-related information, iscsi to show iSCSI protocol-related information, scsi to show SCSI protocol information, and all to show information from all of the above arguments.
