Re: vgcreate of large LUN in 11i v2 (11.23) - BUG

vgcreate of large LUN in 11i v2 (11.23) - BUG

When trying to create a volume group in 11i v2 (11.23) on an Itanium box (rx2600)using a large LUN (210.4 GB), the command hangs indefinitely (>12 hours):
vgcreate vgxx /dev/dsk/c12t0d1

On 11.11, it would complain about needing the extent size increased, but fail cleanly with the message.

When I increase the extent size with the -s option:
vgcreate -s 256 vgxx /dev/dsk/c12t0d1

both 11.23 and 11.11 work as expected (success).

I think this is a bug in 11i v2 11.23. Since my company is currently negotiating a support contract, I can't open a ticket with HP.

Is this sufficient to report the bug???

I would try few more (atleast one more) 210.4 GB LUN before concluding it is a bug.

It could be the result of some problem with that particular LUN.

Actually, the first thing I did was try another 210.4 GB LUN, with the same results. Then, I assigned the original LUN to an HP-UX 11i 11.11 system, and it worked as expected (fail with warning message). On both systems, when I specified the -s 256 option on vgcreate (to increase the extent size), it worked correctly and create the volume group, using the original LUN.

Hi 2,

I also have same siutation here, but I just add a 50GB lun and it will hang indefinitely.

hkgdevt:/dev#vgcreate -p 64 vg01 /dev/dsk/c6t0d1
Increased the number of physical extents per physical volume to 12947.

so it maybe a bug, just share.
