Re: Install (or rollback) to previous version of OS

As I mentioned some time back in the thread your only option is to completely initialize the partition. You can do that by booting this image catalog via TFTP/NFS, ort booting it over a vSCSI connection, or booting it from physical media. It MUST be a manual IPL because you need to get to the point where you can select option 2 to initialize the system. You don't get that far with a normal IPL as that will try to simply replace the LIC and as you can see that's not an option.

Booting from a catalogue on this partition cannot work as it's an i 7.2 partition that needs to be completely initialized and that of course will destroy your image catalog.

Larry,

OK, I have downloaded the latest version of 7.1 from the IBM site.

It is now stored in a Image Catalog on Virtual Partition #2

I want to install this 7.1 onto an existing Virtual Partition #2
currently running 7.2

I have two questions

Question #1
When I run the "verify catalog" it fails with:
Message ID . . . . . . : CPDBC1E Severity . . . . . . . : 30

Message type . . . . . : Diagnostic

Date sent . . . . . . : 12/20/18 Time sent . . . . . . :
18:56:44

Message . . . . : Verification of image catalog V7R1M0 failed with
reason
code 3.

Cause . . . . . : Verification for image catalog V7R1M0 type
*UPGRADE failed
with reason code 3. The reason codes and their meanings are as
follows:
01 - The load source disk unit must have at least 2000 megabytes (MB)
of free
storage space to install from an image catalog (virtual device).

02 - Installation of the release requires additional allocation of
space for
Licensed Internal Code.

03 - The Licensed Internal code media is not supported for
installation over
the current version, release, and modification that is installed.


What am I missing

Question #2
How do I get the partition #2 to IPL from the Image Catalog?

Thanks

John

You have no choice here but to boot an i 7.1 LIC optical media or
tape.
Of course it needs to be sufficiently new to run on POWER8. If you
download from IBM it will be new enough. If you have a tape that
contains SAVSYS from your POWER8 you can use that.

You will get an error that says 'Cannot install LIC over the current
LIC'. (Option 2 in on the install menu) This is because your only
choice is to completely scratch the partition and install new i 7.1
LIC since the system is currently at a higher level LIC. Once that's
installed you will add disks, and install the operating system.

No need to ask why I need to do this, trust me I need to do this.


I have a Power 8 with 4 partitions.

All partitions are currently running 7.2

Currently in the process of updating one partition to 7.3

Want to update one partition back to 7.1 (not even sure if this is
called update? rollback? downgrade?)


At one point in the past I had CD's for 7.1 but can't find them now.

I am under SWMA so I can get 7.1 from IBM (download from IBM web

site,

can't find a way to order 7.1 CD's).


My question is: What is the easiest way for me to install 7.1 on one

of the partitions running 7.2?


Thanks in advance for any suggestions or advice


John
