163.0. "Volshadowed system disk after restoring from backup misses bootblock..." by QCAV01::NRHEGDE (T&E or R&D !?) Mon Feb 10 1997 04:13

Hello !

 Alpha 2100
 OpenVMS Alpha 6.2

 system disk is shadow set. Now we have problem is when we do back on to 
tape from system disk to tape and do a restore it misses the bootblock.
We have to to writeboot after booting from CD to make the restored disk
as bootable.

 We boot from CD and do a backup and restore.

163.1Commands, Please...XDELTA::HOFFMANSteve, OpenVMS EngineeringMon Feb 10 1997 09:253
   What command sequence are you using to create the BACKUP, and
   what command sequence are you using to restore the BACKUP?

    Please also include how the system is booted when the tapes are both
    made and restored...
163.3EVMS::MORONEYUHF ComputersMon Feb 10 1997 11:558
What kind of disks make up the shadowset?

Could you show me a dump of the bootblock after the restore but before
it's repaired?

$ DUMP DSAx:/BLOCK=(START=0,COUNT=1)

163.4Naaaah. Well, difficult to believe, anyhow...POMPY::LESLIEAndy Leslie, DEC man walking...Tue Feb 11 1997 05:2011
    This problem is a classic symptom of forgetting the /IMAGE qualifier.
    Although this may not be the case, the code path used here is so
    thoroughly beaten up by System Managers the world over that I find it
    difficult to believe you've hit the problem as stated in .0.
    
    Anyhow, amongst the queries you will need a ready answer to when you
    IPMT this are: What disk, what tape drive, what 2100 variant, what VMS
    6.2 variant, exact command used, etc. Have you still got the tape? Do a
    BACKUP/LIST and look at the backup command used and report back.

163.5Here I have commands and dumps...QCAV02::NRHEGDET&E or R&D !?Thu Feb 13 1997 00:1368
Hello !
    Probably you are right Andy. My colleague who has done this operation
    might have done some silly mistake, Which I am not able to find out.

 As far as I know standalone did not support backup of shadow set/not recommended
for shadow sets in VMS VAX 5.5-2. Since there is no standalone backup kit
for OpenVMS Alpha  does this procedure we have followed holds good for
shadow set? I have doubt about it.

    
 The procedure followed and dump of DSA is given below.

- Shutdown the running system VMS V6.2

- boot from the bootable v6.2 cd
  >>>b dka600

- select option 4 to get the system management
- Init the tape...
  $init mka500: system

- backup command as follows:-
- $mount/over=id dkb0:
  $backup/log/image/veri/igno=(label) dkb0:system.bck/save
- $dism dkb0:

- restoration command as follows:-
  $init dkb0: 
  $mount/for dkb0:
  $mount/for mka500:
  $backup/image/log/veri mka500:system.bck/save dkb0:

- After restoration, halt the system and boot directly from the system disk
  But it fails to boot.......

- The type of disk we are using = RZ28D-VW
------------------------------------------------------------------------------
* Pl note:-
For your kind information I am typing the hexa-decimal figures from a fax 
output which I have received from the customer place... Pl dont consider the 
Ascii part of the DUMP output. Because Ascii part contains lot of special 
characters which I can not generate on the editing mode.
The Hexa part is OK.......
