pvcreate /dev/rdsk/c7t8d3
pvcreate: IO error on Physical Volume device "/dev/rdsk/c7t8d3".
We're running HP-UX 11.23 on this BL870C. I tried running dd against the disk in question and got equal records and out. I also ran diskinfo -v and it doesn't even recognize the size of the disk: (See Below)
diskinfo -v /dev/rdsk/c7t8d3
SCSI describe of /dev/rdsk/c7t8d3:

Would anyone have any ideas to what could be causing this issue. Could this be the way the devices are presented to our HP-UX host?
Thanks in advance,

Re: pvcreate getting i/o errors
Do you have other working devices presented to this server ?
Discussion about controller flags can be found in the EMC Host connectivity guides found on the EMC Powerlink website.
If you supplied some more info on your environment I might be able to guide you more.
e.g.
Is this the first or only HPUX server in this fabric ?
Are there others working?
If so use the "others" to compare the configurations of presentation, masking and zoning of DMX controllers.

SolutionYes, this eliminates any communication problems such as the fibre or HBA. There's nothing for you to do except get the storage administrator to fix the maps and zones, etc. Remind the admin that this is not a PC since Windows often requires a different setting.
