 3 Syntax as a command:  recover_volume_log pvnames {-control_args}

 5 
 6 Function:  recovers volume logs from dump volumes.  It should be
 7 invoked only if volume logs for physical volumes to be reloaded cannot
 8 be found.  Its input is a list of the latest dump volumes for the
 9 physical volumes in question as specified by the caller.  This command
10 can be used in ring 1 only.

13 Arguments:
14 pvnames
15    are the names of the physical volumes whose volume logs are to be
16    recovered.  All pvnames supplied must be valid physical volume names
17    (i.e., the physical volumes must be valid members of a registered
18    logical volume).

21 Control arguments:
22 -input_volume_desc STR
23    where STR is the attach description used to replace the default
24    attach description "tape_mult_ ^a -system".  The dump volume name is
25    inserted in the attach description at the first occurrence of the
26    string "^a" in the attach description.
27 -working_dir, -wd
28    specifies that the volume backup databases are to be recovered
29    relative to the working directory.  The default is to recover them
30    relative to the >ddd>volume_backup directory.  This control argument
31    can be used to recover the volume logs for physical volumes that are
32    not part of the currently mounted storage system.  This control
33    argument is optional.

36 Notes:  No announcement of the recovery of any volume logs is provided
37 until all volume logs have been recovered or the query for the dump
38 volume name is answered with a period (".").

40 After a recover_volume_log operation is executed, it may be necessary
41 to run a merge_volume_log operation.
