Hi Folks,

This is already posted on Disk & Memory, will post under expert incase there is someone here who has seen this before.

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?
