AIX - stale partition
Hi everybody,
I have a little problem with my AIX 6.1, PowerHA 6.1 LVM mirror. After problem with SAN pathing of our one Datacenter, I have LV at stale state.

Code:
 # lsvg cpsdata2vg
VOLUME GROUP:       cpsdata2vg               VG IDENTIFIER:  00fb518c00004c0000000169445f4c2c

Normally I solve it by command varyonvg for non-concurrent LUNs. I cant find solutions for Enhanced-Capable concurrent LUNs.
I guess that the right way to solve this problem is command varyonvg too. With parameter '-c' for concurrent vary.

Does anyone have experience with this procedure? I cant umount this filesystem right now, so I am curious if I can do this without unavailability or other problem with filesystem.

Thank you.

pvck

PVCK(8) 						      System Manager's Manual							   PVCK(8)

NAME

       pvck - check physical volume metadata

SYNOPSIS

       pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvck checks physical volume LVM metadata for consistency.

OPTIONS

       See lvm for common options.

       --labelsector sector
	      By  default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0.  This parameter allows you to specify a
	      different starting sector for the scan and is useful for recovery situations.  For example, suppose the partition table is corrupted
	      or  lost	on  /dev/sda, but you suspect there was an LVM partition at approximately 100 MB.  This area of the disk may be scanned by
	      using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):

	      pvck --labelsector 204800 /dev/sda

	      Note that a script can be used with --labelsector to automate the process of finding LVM labels.
