i 've just bought 5 new disks.(10KFC 32GB for each). When i used ioscan, i found that size is diffirent.
[MAILSVR:/] diskinfo /dev/rdsk/c6t0d0
SCSI describe of /dev/rdsk/c6t0d0:
vendor: HP 36.4G
product id: ST336607FC
type: direct access
size: 35566480 Kbytes
bytes per sector: 512
[MAILSVR:/] diskinfo /dev/rdsk/c5t11d0
SCSI describe of /dev/rdsk/c5t11d0:

See the last line from each disk's output: it is the sector size. The second disk apparently was once in a VA7xxx storage array. It uses a 520 byte sector size: 512 bytes for data and 8 bytes for additional end-to-end verification.

I pluged 05 new disk (size: 70000000 Kbytes) to our Disk system as attached picture (03 for upper, 02 for lower). beside 05 new disk we also have 04 old disk (size: 35566480 Kbytes)(02 for upper slot 0 and slot 1, 02 for lower slot0 and slot1). 4 old disk are good, but 05 new disk have problem, that is:
when i take pvcreate -f :
=======
[MAILSVR:/] pvcreate -f /dev/rdsk/c5t4d0
Physical volume "/dev/rdsk/c5t4d0" has been successfully created.
=======
and take long time (3 min)
and then, i take vgcreate:
=======
[MAILSVR:/] vgcreate vg02 /dev/dsk/c5t4d0
vgcreate: Physical Volume "/dev/dsk/c5t4d0" contains no LVM information
[MAILSVR:/]

-------
Now i consider that 05 new disks is impossible to use for Disk system 2405 (without Vituarl disk Array).
If it is possible, pls show me how?

hi,

Not sure exactly whether doing a mediainit on the disk would help..just give a try.

mediainit /dev/rdsk/c5t11d0

There are some utilities available in ODE to change the block size of the hard disk..

with best wishes

I already take mediainit, it take me 10 min to do, but the result is same (can't not add or create new vg)
