vxdg import
vxdg -g<DynamicDiskGroupName> [-n<NewDynamicDiskGroupName>] [-s |-d] [-f] [-C] [-o] timeout=<n>] import
Imports the dynamic disk group that is referenced in -g<DynamicDiskGroupName> for use on this computer. You can use its name from the original computer or rename it with -n<NewDynamicDiskGroupName>.
Note:
Microsoft Disk Management Disk Groups do not support the vxdg import command.
The following attributes apply:
-g<DynamicDiskGroupName> | The name of the disk group that is imported. |
-s | Imports the disk group as a cluster disk group. Using this command with the -s option is the only way you can convert a regular secondary disk group to a cluster disk group. With SFW, it is only required to use the -s the first time you create the cluster disk group. |
-d | Converts a cluster disk group to a regular disk group. |
-f | Forces the command; use this option with caution. The -f option can be used to force the import of a cluster disk group when a minority of disks in the disk group is available. |
-C | Clears the disk group's host ID. See more about the host ID below. |
-o timeout=<n> | The -o timeout=<n> option allows the operation to timeout in <n> seconds. This is useful for scripting purposes. |
About a disk group host ID:
When a dynamic disk group is created or imported, all disks in the dynamic disk group are stamped with the computer's host ID. Typically, a dynamic disk group cannot be imported if any of its disks are stamped with a non-matching host ID. This mechanism provides a check in cases when disks can be accessed from more than one host.
In Storage Foundation for Windows, if a dynamic disk group is in use by one computer when another computer attempts to import this dynamic disk group again, the import fails because the host IDs of these two computers are different.
If a dynamic disk group is successfully deported, the host id is cleared and the group can be safely imported to another computer. With SFW, you do not need the -s option. A cluster disk group remains a cluster disk group when it is imported. If you want to change a cluster disk group back to an ordinary disk group, you deport it and then import it with the -d option.
To move a dynamic disk group from one computer to another when the dynamic disk group was not cleanly deported (for example, if the host computer crashed), you must specify the -C option to clear the original host id and stamp a new host id onto the dynamic disk group.
Note:
While importing a cluster disk group as a cluster-shared disk group (CSDG), you must use the -C option.
Example
vxdg -gDynDskGrp1 -nAcctgDynDskGrp import
Imports the dynamic disk group previously known as "DynDskGrp1" and renames it "AcctgDynDskGrp."
