vxvm metadata recover
- 11 years ago
Hi Marius,
Yes, once disk is initialized in Veritas, vxvm will put a private region on the disk which will contain a header or details of that disk. Some of the disks private region in disksgroup contains the whole diskgroup configuration, if you want to see which disks in a diskgroup contains whole diskgroup configuration, you need to execute "vxdg list <diskgorup>"
for e.g see the output below
# vxdg list codb_racdg049
flags: shared cds
version: 140
local-activation: shared-write
cluster-actv-modes: nbcodb01=sw nbcodb02=sw nbcodb03=sw nbcodb04=sw
detach-policy: global
dg-fail-policy: dgdisable
copies: nconfig=2 nlog=2
config disk c10t10d3 copy 1 len=24072 disabled
config disk c10t10d4 copy 1 len=24072 state=clean online <<<<<<<<<<< disk containing config copy
config disk c10t10d5 copy 1 len=24072 state=clean online <<<<<<<<<<<<disk containing config copyOnce you create a filesystem on a logical volume, each filesystem will have its own superblock.
Hope this answers.
