Need help booting Stand alone backup from tape.

[Bob Lombard]

I have a MV 3100-80 with an internal RZ26, TZ30, and external TX85. RZ26 has been replaced following failure of the original. No other devices oin the system

I have a Bootable Standalone backup kit on a TK50 tape.

SHO DEV at th monitor says TZ30 is MKA500
Need help with he command string to boot into
Standalone backup off the TZ30 so we can restore to the RZ26 from the TZ85.

B /r5:e MKA500: ?

I don't have a cd or drive available on this system to boot from the distribution media. Search of the VMS wizard and other thread here was fruitless.

How about just >>> B MKA500 ? I think I'm correct in saying there isn't a "file system" on tape so there would be no [SYSE] directory to look for.

Somehow correct - [SYSE] is used on the system disk. If you create it on another disk, STABACKIT creates [SYS0]. At least that is what my memory tells me.

Another thing it tells me is that the boot root is encoded in the upper 4 bits of R5, so that would be:
>>> boot /r5:e0000000 DEVICE

Bob,

Welcome to the VMS forum!

Yes, Art is completely right.

Be aware, that you will need A LOT of patience!
Booting from tape is REAL slow, and TZ30 is just about the slowest (apart from TU58, that is).
(And I DO hope you have a recent image backup of your previous RZ26).

Success, and patience!

Proost.

Have one on me.

Bob,

welcome to the OpenVMS ITRC forum.

You should be able to directly boot the standalone backup tape. Just tested it on a CHARON-VAX 4000-108:

$ @SYS$UPDATE:STABACKIT $3$MUA0:
...

>>>b mua0
(BOOT/R5:0 MUA0)

2..
-MUA0
1..0..

All - Thanks for the help so far. I'm trying this now. I do have a recent image which I'll pull from the TZ85 one STABCK is up.

[Bob Lombard]

All -
Worked like a champ. STABCKIT loaded from TZ30 in about 110 minutes and the image is coming off TZ85 as I type.

My thanks to all that responded.

[Art Wiens]

And if it would have been a disk booting, Uwe spotted the subtlety of leaving off the trailing 0's to specify the SYSE root(/r5:e0000000).

Funny how the mind works ... I "saw" the 0's but clearly didn't "read" them.

Cheers,
Art
