Disk Mirrors in Reliant Unix - Problem?
Hi Folks,

This one has me a bit confused.

I have a large system running Reliant 5.45 with an EMC 3930 disk array fibre attached. As part of our requirement I implemented host level mirroring in addition to the BCV functionality provided by the 3930.

When the mirrors are split and the second mirror is mounted on a different mount point the size appears to be incorrect.

e.g. the mirror is vdisk302

/dev/vd/vdisk302 41943040 23017929 18877168 55% /ciblive/batch/production/files/dailey

the submirror is vdisk202

/dev/vd/vdisk202 4179408 2680498 1448144 65% /export_aix/ciblive/batch/production/files/daily

If the disk is unmounted and mounted again using the same command the info is correct.

The application is stopped while the mirrors are split and an fsck is run over the second mirror to ensure that it will mount.

Any one seen this before?

Rgds

mkqdisk

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME

       mkqdisk - Cluster Quorum Disk Utility

WARNING

       Use of this command can cause the cluster to malfunction.

SYNOPSIS

       mkqdisk [-?|-h] | [-L] | [-f label] [-c device  -l label] [-d [-d ...]]

DESCRIPTION

       The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.

OPTIONS

       -c device -l label
	      Initialize  a new cluster quorum disk.  This will destroy all data on the given device.  If a cluster is currently using that device
	      as a quorum disk, the entire cluster will malfunction.  Do not run this on an active cluster  when  qdiskd  is  running.	 Only  one
	      device  on  the  SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
	      RAID array is used for quorum disk redundancy).  The label can be any textual string up to 127 characters - and is therefore  enough
	      space to hold a UUID created with uuidgen(1).

       -f label
	      Find the cluster quorum disk with the given label and display information about it.

       -L     Display information on all accessible cluster quorum disks.

       -d     Increase debugging level.  Specify multiple times for more information.  Currently, specifying more than twice has no effect.
