> Hi,

> We are using Veritas Volume Manager 2.5 ( PSTAMP:

> I have 36 configuration copies enabled and online in my disk group (say

> Below is a sample portion of output from   "vxdg list datadg"

> copies:    nconfig=36 nlog=36
> config:    seqno=0.92832 permlen=2101 free=13 templen=2491 loglen=318
> config disk c1t0d0s2 copy 1 len=10631 state=clean online
> config disk c1t2d0s2 copy 1 len=10631 state=clean online
> config disk c1t3d0s2 copy 1 len=10631 disabled
> config disk c1t4d0s2 copy 1 len=10631 state=clean online
> config disk c4t16d0s2 copy 1 len=2101 state=clean online

> As u can see from above, that there are lot of disks initialised with
> large private region(ex:- c1t0d0s2).
>
> Also there are some disks which were initialised with small private
> region (ex:-c4t16d0s2).
>
> Currently disk group is using only 2101 sectors of private region as
> there is one drive with this small private region.
>
> I  ran out of space in the Configuration database.
>
> I have below queries:
>
> 1) Can I disable the configuration copy on c4t16d0s2?
>
> 2) If I can disable this configuration copy which is of small size , can
> the Disk Group now use the private region length of 10631 which is the
> same length on all drives.
>
> NOTE:   1) All the drives have data on them.
>                2) I used a temporary solution:   Removed the disk having
> small private region with vxdiskadm option 4 and replace another drive
> with vxdiskadm option 5. Then uninitialised the old drive with
> vxdiskunsetup.
>                    Re-initalised the drive with large private region
> this time and then used vxdiskadm option 4 and 5 again to transfer the
> data back to this drive.    But, this initiates RECOVERY which eats lot
> of
>                     system resources.
>
>               3) I have several of the drives initalised with small
> private region (default) which I need to disable.
>
>                4) Even after disabling the small private region disks, I
> still have about 26 configuration copies that are online.
>
> I would appreciate any better ideas on how I can fix this issue.

> Thanks a lot in advance.
