There is an AIX subforum here - post AIX issues there next time please.
Some years back I had to get some special files under /dev back, which did not come back from the restore of the mksysb automatically. Here is what I did. The text and comments are in german, but I am too lazy to translate it now You will see by the commands, what I did; hope it helps
Code:
Clonen von Rechnern:
====================
Sichern:
--------
- rootvg mit mksysb sichern >>> wichtig: Create Map files? YES <<<
- Andere VGs (im Bsp. datavg) wie folgt sichern:
savevg -imf /dev/rmt0 datavg
Restore:
--------
- mksysb zurücksichern
- Restore von /dev:
cd /tmp
[tctl -f /dev/rmt0 rewind #Band an Anfang spulen
[chdev -l rmt0 -a block_size=512 #Blockgröße für Streamer auf 512bytes
[restore -s2 -xqdvf /dev/rmt0.1 ./blksize #Blockgröße des mksysb-Tapes ermitteln
[cat ./blksize
chdev -l rmt0 -a block_size=xxx #Blockgröße die in 'blksize' steht setzen
tctl -f /dev/rmt0 rewind
restore -s4 -xqdvf /dev/rmt0.1 ./dev #/dev in /tmp/dev zurück
find . -print | cpio -dmpv /dev #Kopieren von ./dev nach /dev ohne zu über-
#schreiben!
#Allerdings sollte diese nachträgl. zurück-
#gesicherten Devices auf Ihre Rechte über-
#prüft werden. Habe das Flag zum Bewahren
#der ursprünglichen Rechte nich gefunden.
- Andere VGs zurücksichern (Bsp.: datavg):
exportvg datavg #Alte Files/Info der datavg löschen
restvg -qf /dev/rmt0 #Rücksichern der datavg ins System
- Anschließend den cfgmgr starten

Every 3 months we have to do backups (smitth mksysb/lsmksysb + tar) on at least 30 workstations. We have to carry around 2 external tape drives to connect to them.

In the several backups we do, we do a "smitty savevg" on about 15 different servers at the same time. Typing all the options on the savg screen is kind of long.
Is it possible to invoke the "smitty savevg" backups as command line (aix 4.2) but using all the options we always enter ?

Hello,
I use commands savevg & mksysb to do backups on an AIX server.
Frequently, I have a return code 3.
I would know why, but after searches, I did'nt find.
If somebody know ... Tell me.
Thanks.

Other then creating a exclude 'all' file. Is there a way to just create a nim savevg resource that contains just the minimum info to restore a vg. The vg's dirs and files are being backed up. -pete (0 Replies)

Hi All,
I need to take the backup of non-rootvg using savevg utility. I would like to know, if I can take the backup without shutting down the application & database. Is it possible to take the savevg backup safely when users are working on the system ?
Regards. (1 Reply)
I am trying to restore files from savevg.
I used to smit restore and gave the file location.
Savevg is taken to a mount point from San storage and not tape back up.
Can I restore just a directory from savevg?

norewind_close_disabled - determine whether access to tape device special files without the no-rewind-on-close option is allowed
VALUES
Default
Allowed values
DESCRIPTION
Note: this tunable was named in releases prior to HP-UX 11i v3.
This tunable notifies the tape driver whether it should allow access to device special files without the no-rewind-on-close option. When
this tunable is on, the tape driver will fail any open on a tape device special file that does not have the no-rewind-on-close option (that
is, or with a status of
The tunable allows the safe sharing of tape devices in SAN tape backup solution configurations. The disabling of device special files
without no-rewind-on-close in a SAN tape backup solution configuration prevents the accidental sending of a rewind command on close from
HP-UX systems via standard tape commands like which would corrupt a backup in process.
Who Is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect immediately.
When Should the Tunable Be Turned On?
This tunable should be turned on if the system is going to be used in a SAN tape backup solution configuration.
What Are the Side Effects of Turning the Tunable On?
The tape driver will fail any open to a tape device special file that does not have the no-rewind-on-close option with a status of This
behavior prevents the usage of any tape device special file without the no-rewind-on-close option.
When Should the Tunable Be Turned Off?
This tunable should be turned off if the system is not part of a SAN tape backup solution configuration or the system utilizes will not
function unless it has access to device special files without the no-rewind-on-close option.
What Are the Side Effects of Turning the Tunable Off?
A rewind may be issued accidentally from this system on close, possibly corrupting a backup being issued from another system on the SAN.
What Other Tunables Should Be Changed at the Same Time?
None.
EXAMPLES
Query the current value of the tunable:
