New disk has 0 size

[TMcB]

I have installed a new 4Gb disk. the server is running 10.20 (800).
The problem is that although it sees the new disk in ioscan and sam. I cannot create any volume gorups on it as it says it has 0 size.

> diskinfo /dev/rdsk/c1t9d0
SCSI describe of /dev/rdsk/c1t9d0:
vendor: SEAGATE
product id: ST34573WC
type: direct access
size: 0 Kbytes
bytes per sector: 0

Any help is greatly appreciated

What's the output of diskinfo -v

[Ravi_8]

Hi,
have did #pvcreate -f /dev/dsk/c1t9d0, still if you are seeing 0 bytes perform low level format(#mediainit -f /dev/dsk/c1t9d0) on that disk

diskinfo -v gives :

ioscan -f
If you have online diagnostics installed
software.hp.com/SUPPORT_PLUS/
you can run a tools-info-run to get all
information on the hw.

If the disk has a 0 size, then chances are good that the disk is bad. I would go ahead and replace the disk. If it is an HP disk, place a hardware call, otherwise call the vendor you bought it from and have them send you a replacement.

[Rainer von Bongartz]

Ok, you should do mediainit as ravi said

[MANOJ SRIVASTAVA]

Hi Terry


Proceed like this


1.ioscan -fnC disk | grep c1t9d0 should tell you whether the disk is being sensed or not. Then do a insf -e.

2. Do a mediainit -f /dev/rdsk/c1t9d0.

3. pvcreate -f /dev/rdsk/c1t9d0.

with this you you should be able to get the correct size and the disk usable.

Hi Terry!
You should try what Manoj told you, but you can try to run a dd on that disk by doing:
"dd if=/dev/dsk/cxtxdx of=/dev/null bs=64"

if it gives something like:
23451+0 records in
23451+0 records out

it's OK. But if it gives some different values then it needs to be changed.

good luck.

[John Bolene]

When this happens to me, the disk is bad and I get HP to replace it.

[TMcB]

Hi

when I try to run mediainit or dd
I just keep being told that the device is busy

Thanks

I'm just wondering how you have the drive connected. It could be a cabelling problem, perhaps incorrect termination or the drive may be incompatible with the slot you've place it in to.
I think more info is required on the disk and it's physical cableing.

Although, if it did work before, then it sure sounds like a disk problem.
