vgcreate hangs
I have 5 BL860C loaded with HP-UX 11.31, and all 5 box are attached to a HItachi A9500 Series array.
I was able to do pvcreate successfull, but when i do vgcreate it hangs.
ioscan shows all the disks claimed
dd command also hangs
This a is a new disk array, what could be the possible issue.
Is this the HW issue or is there any different way to create volumes in 11.31

Re: vgcreate hangs
The 'vgcreate' command needs to write LVM metadata to the physical disk. Its hanging is consistent with 'dd' hanging. Claimed hardware only indicates that the correct drivers are present and that at one time the hardware responded to a probe.
You have a hardware or connection issue with the array.

Re: vgcreate hangs
Check your zoning, how does you do it? Make sure you create a separate grouping for windows machine and hpux machine

Re: vgcreate hangs
As suggested above, check the SAN zoning for the assigned LUNs.
Can you run `ioscan -fnC disk` again and see the status of the devices.
If you use `ioscan -kfnC disk` devices are not scanned and the device status are taken from kernel image.
Thanks,

Re: vgcreate hangs
#diskinfo command to check if the disk is responding
#dd command to check if the whole disk is readable
I suspect you are having problem from diskinfo. It could be fibre channel driver version update needed to work with the array.
Check the FC adapter used and get the driver from http://software.hp.com

Re: vgcreate hangs
Have you verified the HBA model and Firmware compatibility with the new storage?
Try removing and create a new zone ,
Try allocating smaller size LUN if the current one is of big size.
LVM 2 is available in v3 try creating vg in lvm2
Thanks!!
