vxvm:vxassist: ERROR: Cannot allocate space to replace subdisks
I want to evacuate a 17 Gb disk to a new 68 Gb disk and get the following error:
/etc/vx/bin/vxevac -g prdar1_prcm10_dg -t taskid_100 prdar1_prcm10_dg00 prdar1_prcm10_dg24
vxvm:vxassist: ERROR: Cannot allocate space to replace subdisks
vxevac: Aborting disk evacuation
The diskgroup prdar1_prcm10_dg is a striped diskgroup which contains 6 x 17 Gb disks.
We want to replace these disks with 6 x 68 Gb disks.
We always use "evacuate disk" to replace the old disk but today we get this error messages.
Before we do a evacuate the 17 Gb disk is 97% in use and the new disk 0%. After the evacuate failed the 17 Gb disk 62% in use and the new 68 Gb disk 8% in use.
We are using veritas 3.5 on HP-UX 11.23 PA-RISK system.
Why get we this error messages? There is enough free space on the disks and how can I explain that two of the four volumes are evacuated to the new disk and the other two doesn't?

Thanks for your suggestion but I think this is not the issue.

Re: vxvm:vxassist: ERROR: Cannot allocate space to replace subdisks
Have you read the link?
"Unable to evacuate, mirror, or replace disks with VERITAS Volume Manager (tm) 3.2 or 3.5 if disks have been initialized under Volume Manager 3.1. "
Is this the case with you.
From vxdisk list i can only see one difference but I am not sure of that.
config priv 000017-000247[000231]: copy=01 offset=000000 disabled
config priv 000249-000744[000496]: copy=01 offset=000231 disabled
log priv 000745-000854[000110]: copy=01 offset=000000 disabled
in target disk it is disables.
Gurus can any one through some light on this.
BR,
Kapil

Re: vxvm:vxassist: ERROR: Cannot allocate space to replace subdisks
Think you better open a support case. ;) (but first go to vxvm 4.1 ;))
Best Regards,
