Before merging 2 disk groups, I did a verification by adding “-o verify”. However, the merge took place. Please refer to my steps:
# vxdg import gwarpttempdg
# vxdg -o verify join gwarpttempdg freedg
VxVM vxdg INFO V-5-1-13416 Disk group freedg: Alignment will be reduced to 1 sector(s)

Part of “vxdg” manpage:
vxdg [-o {verify|override}] join sourcedg targetdg
join Moves all objects from the imported source disk
group, sourcedg, to the imported target disk
group, targetdg. At the conclusion of the move,
sourcedg is removed.
The source disk group and target disk group to be
joined must both be either private or shared. If
one disk group is private and the other is shared,
deport and reimport the private disk group as
shared before performing the join.
The -o verify and -o override options modify the
default behavior of a move, split or join opera-
tion that includes disks from an EMC array. Usu-
ally, if the EMC license is present, the EMC disk
compatibility check is performed for each disk
that is involved in a move. If the compatibility
check succeeds, the normal operation takes place.
An internal check is made to ensure the configura-
tion has not changed since the compatibility check
was performed. If it was changed, the entire pro-
cess is retried.
If -o verify is specified, the access names of the
disks to be moved are returned but the operation
does not take place.
If -o override is specified, the operation is per-
formed without any EMC checking. |
