about the disk!

[leyearn]

system modle :rp5470
os:11i
diskSystem: fc10
we added one disk into the fc10 enclose
then I rebooted the system
#ioscan -fnCdisk
the added disk's special devices appeared
and the S/W State:CLAIMED
but
#diskinfo /dev/rdsk/c6t8d0
Size:0 Kbytes
bytes per sector:0
what'wrong with the disk?

[KapilRaj]

I am not sure about the fc10's but if this is EMC , EMC uses some device files as pointers in a chain and they would appear as normal disks but with 0 bytes in size.

does this disk has something wrong with static?

Hi

check with this
#dd if=/dev/rdsk/c6t8d0 of=/dev/null bs=1024k

if you get any errors, disk is corrupted else reinsert the disk and try again

It hanged when dd

Then get the drive replaced - the drive is faulty.

If a drive reports 0 Kbytes, generally it is no good.

Hi,

Is a **new** disk? Have you create physical volume for use in LVM volume group?
#pvcreate -f /dev/rdsk/c6t8d0

Rgds.

[Michael Tully]

The 'diskinfo' command reports about the physical disk. The 'pvcreate' command tells the LUN it is now an LVM disk. Unless diskinfo reports some size of the disk 'pvcreate' will fail in any case.

Hi,
If you are sure that the disk is properly seated then,make sure you are tracing the correct device file.
