Restoration of the entire file system is not required if a dump
tape is lost or bad. However, restoration is recommended.
Step 1. Verifythe new system is large enough to contain all
thedatarestoredfromtapebyusingtheUNIXdf
command.
The /arch3 file system is used throughout this
example.
Step 2. Run the xfsrestore command.
Step 3. Checkpoint the FileServ database. For information,
see “Dump Data” on page 4-9.
Step 4. Perform a recovery audit by using fsaudit -r
-f. For information, see “Audit Database” on
page 4-17.
If the fsauditcommand fails with a message that
indicates a relation parent unknown, the relation
point parents are not on the dump tape. This situation
occurs if:
• All files are not recovered from the dump tape
(bad dump tape).
• Dump is not made after a DataClass relation is
added to a directory.
