boot problems after building boot disk on SAN disk

I re-built a 3 11.23 systems on SAN boot disks. These systems had been on local disks. 2 of Them have had various problems during the various boots that the install goes through.

As a test I re-booted from the local disk and imported the new SAN boot disks as vg00x. I then did a lvlnboot -v vg00x and got:

Boot Definitions for Volume Group /dev/vg00x:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c4t0d1 (0/12/0/0.10.0.3.0.0.1) -- Boot Disk
Unable to query the I/O interface: Parameter error.

The only thing I did different was on the first I let home default as 64MB then after it was built I changed /home to /root and added a larger /home then moved the home files from /root to /home. On the 2nd and third using the install dialog I renamed /home to /root and added a new larger /home. The net effect was the LVOL order was changed. (IE 1st /stand,*swap,/,/root,/opt,/tmp,/usr,/var,/home (added later); for 2nd and third /stand,*swap,/,/home,/opt,/root,/tmp,/usr,/var.

Hi,

Please execute the following command.

# lvlnboot -R

Then again run

# lvlnboot -v

Please let me know still if you have the same error.

I think I have an issue with the HBA itself. Rebuilt the systems using the local disk and let them overflow onto a SAN disk.

Not sure whats going on though 3 systems connected to same SAN with same type HBA cards. 1 system SAN boots fine 2 systems have problems.

All the things I can find about firmware upgrades are for Intergrity systems. These systems are PA-Risc. Not even sure how to extract the relevant firmware info.

When I tried booting from local disk and vgimporting the SAN boot disks to vgsan00 and trying lvlnboot -v vgsan00 got good results for the system that works and bitter complaints from the 2 that had problems.

See previous note. I am currently moving forward with the mixed local/SAN layout. Will mirror to a local/SAN pair and when I have some way to upgrade the firmware on the HBA I will mirror to a a SAN only and try to boot from the new mirror.

If your SAN enviroment is something new, then yes it likely is incompatibility with your HBA.
You should check on this and see if there is a recommendation as to which HBA is compatible.

On the other things...I am not sure why or what for certain you are doing.

[I changed /home to /root and added a larger /home then moved the home files from /root to /home.]
>>>WHY? Just leave home alone, and increase it. Create /root.
Why are you doubling your work??????

[I tried booting from local disk and vgimporting the SAN boot disks to vgsan00 and trying lvlnboot -v vgsan00 ]
>>>WHAT? You booted up using the vg00 which resides on local disk and you vgimported some kind of "vgsan00" disks that are bootable into the same server with a vg00 that is bootable and running. WHAT? are you trying to do?

If you want to have SAN boot disk, then pvcreate the SAN disk using the proper make-it-bootable commands and mirror up the lvols, etc.

Let us know what your hardware is so we can suggest a solution on your possible HBA issue.

Telling us your steps on just how your trying to mirror vg00 to some SAN disk would be helpful.
