custom boot cd for a DS15

[Stefan Kirchner]

How can I create a custom boot cd for a DS15 ?
I need one custom boot cd to make vdump/vrestore. I have only a installation cd from 2002.
Thanks

hi stefan,

u don't need a custom cd to make backup or os backup in tru64.

1)btcreate - this will create a bootable OS tape. You could boot this tape and it will restore the OS for you.

OR

2) boot the OS cd and go to unix session (or single user mode) or something like that...(i can't really remember). run `scu scan edt` to detect the disks and tape drive. Confirm this by running `scu sho edt`. Then perform makedev to create the file for disk and tape devices. Then, partition the disk accordingly. Create ufs or advfs filesystem. Then you can continue restoring with vrestore (if you backup using vdump)

eg of creating devices for disk in tru64:
# scu sho edt

CAM Equipment Device Table (EDT) Information:

Device: CD-224E Bus: 1, Target: 0, Lun: 0, Type: Read-Only Direct Access
Device: BD018122C0 Bus: 2, Target: 0, Lun: 0, Type: Direct Access
Device: BD018122C0 Bus: 2, Target: 1, Lun: 0, Type: Direct Access

i would to create for disk in bus 2 target 0 lun 0.

Formula :
Lun0 = rzaNN or rzNN
lun1 = rzbNN
.
.
lun7 = rzhNN

NN = (8 x scsi bus number)+scsi target ID

therefore:
bus 2,tgt 0,lun 0
lun 0 = i could use rza or rz. In this case, i use rz

NN = ( 8 x 2 ) + 0
NN = 16

therefore : rza16

Execute makedev to create the files:
# cd /dev ; ./MAKEDEV rza16

Confirm its the right disk:
# file /dev/rrza16

The above only applicable in tru64 v4.0

If tru64 v5, just run hwmgr -scan scsi and hwmgr -view scsi. In v5, it will create automatically the special file.

Does a DS15 support anything older than V5.1A
with NHD7?

I find "dn_setup -boot" to be helpful.

Knowing nothing, I'd assume that a CD-ROM
for V5.1B (perhaos V5.1B-x, where x = 1, 2,
3, 4) would work better than some old V5.1A
CD. What's on your "installation cd from
2002"? Why do you want a "custom boot cd"?

[Stefan Kirchner]

Installation CD is Tru64 V5.1B, official delivered version and if I boot the DS15 with this cd, the system crashed with unsupported hardware event.
Support guy guess btcreate is not a very safe tool.

I have a CD-ROM kit with "Version 5.1B-4"
("December 2006"). It also has an "NHD-7"
CD, and a DS15 is much newer than my junk, so
I don't know if any of this stuff would work
better than what you have already, but I can
say that such things exist.

You don't use the OS cd but the NHD7 CD to boot from

to create abootable CD see http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=837055

where Erik van Dijken gives a procedure to create one.

Thanks for all details.
I merge the original installation cd with the nhd7 and it works.
