Seeing new EMC disks as 0-bytes
disk is /dev/rdsk/c13t0d2
SCSI describe of /dev/rdsk/c13t0d2:
vendor: DGC
product id: CX700WDR5
type: direct access
size: 0 Kbytes
bytes per sector: 0
-----------------------------
disk is /dev/rdsk/c13t0d3
SCSI describe of /dev/rdsk/c13t0d3:
vendor: DGC
product id: CX700WDR5
type: direct access
size: 37764096 Kbytes
bytes per sector: 512
If I try to vgcreate using one of the 0-byte luns, it dies "Device Busy". Also, anything like an ioscan or a diskinfo that goes against those 0-byte luns takes minutes. Any ideas ?

Re: Seeing new EMC disks as 0-bytes
Try cross checking with sym commands.
#sympd list | grep dev/rdsk/c13t0d2
You will get the output size like this.

-------------------------------------------
Last column all says the size, i.e 34526 is 36GB disk , and 8632 is 9GB disk ,
if still shows zero , it seems problem with creating the Lun or may be the disk is having problem.
Hope this may help you,
Raj.

Re: Seeing new EMC disks as 0-bytes
They look just like what you report. Or it could be the post before mine is right.
Take a look with mstm or xstm or cstm and you might get an idea which it is.
I'd like to seee the ioscan output if it weren't past my bedtime. Still, it would be useful to verify my quess.

#inq -clariion
and
#inq -clar_wwn
to check if you actually correctly see the devices and they are logged in properly with the SP's .
If not then deregister the host from the clariion and remove the LUN's from the storage group and destroy the storage group .Then reregister the host and put back the storage group and the LUNs in it . Some times it helps . YOur apps have to come down though .
