Hi,

Why?

/dev/dsk/c3t6d0 /dev/rdsk/c3t6d0

That is because of max_pe_per_pv limitation.

You are going to have to re-create the volume group to solve this problem and specify either the new maximum number of physical extents per volume and/or increase the physical extent size. It's a common problem so don't feel too bad about it.

It looks like your original VG00 was created with 9-10GB disks. The max size disk you can have with your current VG00 configuration is:

PE SIZE x TOTAL PE = 4MB x 2500 = 10000MB = 9.76GB

The only way you are going to be able to use the entire disk is to install Ignite/UX, if you don't already have it, create a make_tape_recovery tape (preferably 2) and then boot from that tape.

When you boot from an Ignite tape it allows you to choose which disks you want VG00 to be set up with. This will allow you to include the 36GB disk and make full use of it.

Do you NEED to have this disk as part of VG00? Can you create another VG and LVs and move data around to make use of the new disk? That would be easier than reinstalling your system with Ignite.

Otherwise you have taken a perfectly good 36GB disk and turned it into a 10GB disk.

Hi,

create vg again with vgcreate -s ....
select size more than 4MB.
