Full Discussion: Reuse a LUN
Homework and Emergencies Emergency UNIX and Linux Support Reuse a LUN Post 302688391 by Peasant on Sunday 19th of August 2012 03:00:09 AM

You will need to run on server-1 (on which you want to remove the LUN from)

1. vgdisplay -v the group, and write down the LUN's/disks that are used in it.
2. vgexporton that volume group.
3. pvremove on disks that are inside that volume group.
4. Depresent the disks from storage side.
5. Run ioscan -fnC disk, and check for NO_HW
6. Run rmsf -H on NO_HW devices

You have now removed the Lun(s) from server1.

Present the lun's to server 2, run ioscan -fnC disk.
If you are running v2, you will need to run insf -e to create devices, on v3 they will be created after ioscan.
Verify the results with xpinfo, or similar tool.
Run pvcreate on those rdsks created (you don't need -f if you ran pvremove on server1), only per one path is enough of course.
Use the LUN in new or existing volume group.

Notice, if you are running v2 and you are using multipath, you will need to add both paths in your volume group via vgextend (existing) or vgcreate (new).

Hope that helps.
Regards
Peasant.

NAME

       fcinfo - Fibre Channel HBA Port Command Line Interface

SYNOPSIS

       fcinfo hba-port [-l] [HBA_port_WWN...]

       fcinfo  remote-port [-ls] [-p HBA_port_WWN] [REMOTE_port_WWN...]

       fcinfo [-V]

       fcinfo [-?]

       fcinfo  is  a  command  line interface that collects administrative information on fibre channel host bus adapter (HBA) ports on a host. It
       also collects data on any fibre channel targets that may be connected to those ports in a Storage Area Network (SAN).

   SUBCOMMANDS
       The following subcommands are supported:

       hba-port

	   Lists information for the HBA port referenced by the specified HBA_port_WWN. If HBA_port_WWN is not specified, all  fibre  channel  HBA
	   ports on the host will be listed.

       remote-port

	   Lists  the remote-port information for those remote ports that are specified. If no REMOTE_port_WWN is specified, all remote ports that
	   are visible through HBA_port_WWN are listed.

OPTIONS

       The following options are supported:

       -l, --linkstat

	   Lists the link error statistics information for the port referenced by the specified HBA_port_WWN or REMOTE_port_WWN.

       -p HBA_port_WWN, --port HBA_port_WWN

	   Retrieve remote port information from the HBA_port_WWN of the local HBA port on the host. The -p option  can  only  be  used  with  the
	   remote-port subcommand and is a mandatory option.

       -s, --scsi-target

	   Lists  the SCSI target information for all remote ports the user has asked for. The -p, --port option must always be specified and must
	   be a valid HBA port on the host. This HBA port will be used as the initiator for which to retrieve the SCSI level  target  information.
	   Note that this will only function on remote port fibre channel World-Wide Names that support an FC4 type of SCSI.

       -V, --version

	   Prints the version information.

       -?, --help

	   Prints the usage information.
