Re: D-IPL from Tape on Power6 520

Hi,
What I figured out so far is that I indeed should D-IPL the box from a
cdrom that contains the same LIC version as the backup on Tape and
from there use the tape as alternate installation device. That has
worked for me in the past as well. But I'm still struggling with
getting at a CD with the same LIC version as the one on the tape.
Should I have made a save of the LIC and used that as boot image?
br, Rolf

Single lpar or multi lpar machine? If multi lpar is the card allocated

to

that lpar?

It's a single partition.

I am catching a thread about the 3573 (aka TS3100) having two scsi
addresses. One for the tape library and one for the tape device. The
address for the tape drive must be 0.

Did you use your HMC to flag it as your alternate IPL device?

Here things get interesting. I do not have a HMC, only the ASMI as
it's a lab box.And I have to admit that I figured the "flagging" an
alternative IPL device was done on every IPL (think: BIOS boot order
kind of thing) and was not something machine dependent.

- The #5749 is supported on POWER5 systems, with IBM i 6.1.
- The Fibre channel controllers (#5749, #5774 and #5735) will allow IPL
directly from SAN attached tape (alternate IPL) but only when used on
POWER6 systems.

Yeah, that was the first thing I checked because I also knew that
there might be some probs with unsupported configurations here.

An alternative is to IPL from CD/DVD and install NOTHING from that

CD/DVD

but tell it to jump over to your alternate installation device.

I tried that as well but it failed because of a mismatch of the LIC on
the CD and the LIC on the tape. Here I have to add that I just
installed the CUM PTFs prior to backing up the box.

John, I didn't have that much bad luck. The box already has an optical
drive. Yet (see above) I'm too newb to use it properly :)

Thanks so far, best regards, Rolf
