5. The quorum and IBD volumes are restored. All other volumes are left intact and
are claimed by the recovered primary node if they are not corrupted.
If they are corrupted you have to:
a. disable the cluster service and cluster disk driver (the steps required to do
so are described in MSDN Q176970)
b. restart the system
c. reestablish the previous storage structure
d. enable the cluster disk driver and cluster service
e. restart the system
f. restore user and application data
6. Restore the remaining nodes. See
node" on page 97.
Merging P1S files of all nodes for EADR
Another step is required for EADR after backup has been performed. It is impossible
to collect enough information to configure the disk in Phase 1 for shared disk volumes
that are locked by another node during backup. This information is necessary to
enable the restore of all shared cluster volumes. To include information on shared
cluster volumes in the P1S files for all nodes in the cluster, do one of the following:
• After a full client backup has been performed, merge the information on shared
cluster volumes in the P1S files for all nodes in the cluster, so that the P1S file of
each node contains information on the shared cluster volumes configuration.
• Move all shared cluster volumes temporarily to the node which you are going to
back up. This way all required information about all shared cluster volumes can
be collected, but only that node can be the primary node.
To merge the P1S files of all nodes, execute the mmerge.cmd command from the
Data_Protector_home\bin\drim\bin:
mmerge p1sA_path ... p1sX_path
Where p1sA is the full path of the first node's P1S file and p1sX is the full path of
the P1S file of the last node in the MSCS. Merged P1S files will be saved in the same
directory as the source P1S files with the .merged appended to their filename (for
example, computer.company.com.merged). Move the original files to another
location and then rename the merged P1S files back to the original name (delete the
.merged extension).
