Hi Experts , I want to start migrating our AIX 6.1 to AIX 7.1 . I am planning to use alt_disk_migration . Chris gibson has awesome documentation in the internet. However I am running into an issue with EMC odm filesets . So my current OS is AIX 6.1. and I have this :
-------------
But if I migrate to AIX 7.1 these are not compatible, because bos.rte will be 7.1. ( i tested trying to install those on a clean AIX 7.1 and failed)
For AIX 7.1 we need the EMC.CLARION.AIX.rte 6.0.0.2 or something. So Now I have dilemma here . I can't install those before migration because we are still in AIX 6.1 . But I can't migrate to AIX 7.1 with EMC.CLARiiON.aix.rte 5.3.0.9, because it is not good with AIX 7.1. See the problem I have here. I was thinking uninstall those before migration , then I feel like this is too risky for production environment. Any body has any idea, all the help will be appreciated very highly !

I don't think you really need your disks during the migration ;-) After you made alt_rootvg, you can wake it up and remove the filesets. After booting in new AIX you install the new versions.
Waking up alt_rootvg: alt_rootvg_op -W -d hdiskX
Removing filesets in alt_rootvg: INUCLIENTS=1 chroot /alt_inst /usr/sbin/installp -u 'EMC.CLARiiON.*'
Putting alt_rootvg back to sleep: alt_rootvg_op -S -t -d hdiskX
Of course, if your rootvg doesn't reside on EMC storage using NPIV or dedicated FC.
Thanks agent.kgb.
You can't wake the altinst_rootvg in this situation . This will only work if it is a TL upgrade. otherwise
will give you some sort of error , saying can't wake up the vg because current version is lower than alt_rootvg, something like that. I am thinking doing some sort of post install script . keep you posted

The other thing, of course, is to ask EMC for their advice.
Also, IBM support should have some ideas. I would hope that the binary compatibility between AIX 6.1 and AIX 7.1 would let you at least install/migrate AIX and reboot.
If I read/understood you correctly - it is sad that EMC will not permit you to update their drivers on AIX 6.1 (or on the alt_install).
And, thanks for your willingness to keep us current on your progress!
Thanks for everyone for trying to help .So i did test migration with NIMADM , After migration i upgraded EMC odm, now it looks like below (not sure why it is showing two of same fileset) . so far it works, this server has only two LUNs, (test server) no application or anything running on the server. I will know more when I do that on the real server, hope everything runs okay . I need to figure it out how to put that in the lpp_source. EMC is such a pain , one image file came with Symmetrixc, clariion, CELERRA together, i need to separate those install only CLARiiON. I need to figure it out how to add that only in the lpp_source, smit installp take care of that easily, not in this case, or maybe I am just dumb .

reboot and ready. But if you've read the whole output, you seen that I've used lpp_source for the update. I don't have EMC ODM filesets in the lpp_source, but it is not so difficult to do. If they were there, they were updated together with the base OS.
something like:
then you don't even need to update them manually and to reboot the server again.
Wow ! agent.kgb you rock, I will try that and let you know. How did you get all these output? , looks like your environment is same like ours. You truly are helpful person
Greetings Experts,
We are migrating from AIX to RHEL Linux. I have created a script to verify and report the NULLs and SPACEs in the key columns and duplicates on key combination of "|" delimited set of big files. Following is the code that was successfully running in AIX.

Hi all,
I hope I'm putting my first post at this site into the right forum. I need help finding the EMC disk driver for AIX version 5.3. I have some new EMC disk presented to a backup server of mine, and right now the EMC hdisks show up looking like this in an lsdev:

This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)
