HP-UX 11iv3: vgcreate 1.0: Unable to read the physical volume

[AnaP]

Hi,

I've started playing with HP-UX 11iv3 and I'm having problems when creating a vg with version 1.0:

# pvcreate -f /dev/rdisk/disk0
Physical volume "/dev/rdisk/disk0" has been successfully created.

# vgcreate -V 1.0 /dev/vg09 /dev/disk/disk0
Increased the number of physical extents per physical volume to 9215.
vgcreate: Volume group "/dev/vg09" could not be created:
Unable to read the physical volume.

If I create a vg with version 2.0 with the same disk, it succeeds:

# vgcreate -V 2.0 -s 8 -S 4t /dev/vg09 /dev/disk/disk0
Volume group "/dev/vg09" has been successfully created.
Volume Group configuration for /dev/vg09 has been saved in /etc/lvmconf/vg09.conf

# diskinfo /dev/rdisk/disk0
SCSI describe of /dev/rdisk/disk0:
vendor: DGC
product id: CX700WDR5
type: direct access
size: 37748736 Kbytes
bytes per sector: 512

I’ve tried the same operation in the server with an internal disk instead of a Clariion disk and the creation has worked correctly:

# pvcreate -f /dev/rdisk/disk13
Physical volume "/dev/rdisk/disk13" has been successfully created.
# vgcreate -V 1.0 /dev/vg01 /dev/disk/disk13
Increased the number of physical extents per physical volume to 17501.
Volume group "/dev/vg01" has been successfully created.
Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf

Any idea?
Thanks in advance,
Ana

Ana,

Have you confirmed that the Clariion is running at least version 26 of FLARE and that you have the "failover mode" set to 4 (ALUA)

Hi Duncan,

This was exactly my problem. I've talked to storage guys and after changing the failover mode, the problem is solved.

Thank you very much

Ana

ALUA set to 4 solved the problem
