restoring backup after adding new disks question

[dpsmith]

Hello.
I added 5 new 18GB scsi drives to replace our 5 9GB drives.
I did a backup using the Tivoli software.
RS6000 F50 with a tape backup.
OS is mirrored.
Data is on the 5 RAID5 drives.
It's all data not the OS.

I did this before on AIX 4.1 but the update to 5 has changed my directions somewhat.
I go to restore and I get a warning that I need to go from 64 to 128 PPs.
I'm then taken to a screen where I'm given the option to change the PPs but it doesn't save my chages.
It just gives me the error screen again.

Can anyone give me the step by step or point me to the step by steps?
Thanks.

If I understand what you are asking:

With 5 18 GB disks in your RAID5 array, you will have to put the array into a different volume group (assuming you are trying to put it in the old volume group) because the size of the array is so much larger than the old array. You are bumping up against the limit on the number of physical partitions for a disk.

smitty steps:

1. smitty mkvg (to create a new volume group with the raid5 array). The system will set the size of the PPs automatically.
2. smitty mklv (to create the logical volume for your data)
3. smitty mkjfs (to create the filesystem)
4. mount <newfilesystem>
5. Restore.
