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.

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.

partition - make a partition table SYNOPSIS
partition [-mf] device [type:]size[+*] ... DESCRIPTION
Partition makes a partition table on device using the types and sizes given. It may be used in combination with repartition(8) for auto- matic installation of Minix. You may give up to four type:size[+*] specifications for the partitions. You may also specify holes before, between, and after the parti- tions. A hole differs from a partition specification by not having a type. The first hole is by default 1 sector to make space for the primary bootstrap and the partition table. The other holes are 0. The type field is the type of the partitition in hexadecimal. The size field is the partition's size in sectors. The + or * may option- ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active. Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1. Some operating systems care about this. Minix and MS-DOS do not. OPTIONS
-m Minix only, no need to pad partitions. This is the default for subpartition tables. -f Force making a partition table even if the device is too small. EXAMPLE
partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+ Partitions disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end of the disk. (06:0+ would have been ok too, it's just a sanity check.) SEE ALSO
