Example
At the command prompt type clubar r c:\temp\ClusterDatabase force
q: to restore a MSCS Database from c:\temp\ClusterDatabase.
For more information on clubar usage and syntax, see the clubar.txt file located
in the Data_Protector_home\bin\utilns.
If the Data Protector shared disk on the Cell Manager is different from the quorum
disk, it has to be restored as well. To restore the signature of the Data Protector shared
disk and any other application disk, you should use the dumpcfg utility included in
the Windows 2000 Resource Kit. For details on using dumpcfg, run dumpcfg /?
or see the Windows 2000 Resource Kit documentation. For more information on the
problems with hard disk signatures on Windows, see MSDN article Q280425.
You can obtain the original hard disk signatures from the SRD files. The signature is
a number following the volume keyword in the SRD file.
Example
-volume 5666415943 -number 0 -letter C -offslow 32256
-offshigh 0 -lenlow 320430592 -lenhigh 2 -fttype 4 -ftgroup
0 -ftmember 0
-volume 3927615943 -number 0 -letter Q -offslow 320495104
-offshigh 2 -lenlow 1339236864 -lenhigh 0 -fttype 4 -ftgroup
0 -ftmember 0
The number following the -volume keyword is the signature of the hard disk. In this
case the SRD file stores information about a local hard disk (with drive letters C) and
quorum disk (with drive letter Q). The signature of the quorum disk is stored only in
the SRD file of the active node (at backup time), because it keeps the quorum disk
locked and thus prevents other nodes from accessing the quorum disk. It is therefore
recommended to always back up the whole cluster, because you need the SRD files
of all nodes in the cluster, since only all SRD files together include enough information
to configure the disk in Phase 1 for shared disk volumes. Note that a hard disk
signature stored in the SRD file is represented as a decimal number, whereas dumpcfg
requires hexadecimal values.
