ioscn gives NO_HW

[prash_1]

dear guru's
when i am giving #ioscan -fl to list hardware status I got NO_HW at hardware path
0/3/1/0.13.0
at this path my ultrium is connected
then I chacked softerware for it it is also present.
because of this my backup is stoped.
What is the problem & how can I over come From it

If ioscan reports NO_HW, your system cannot see the drive. Check all connections and cables but consider to have a bad drive and replace it.

if using fc connection
check with fcmsutil /dev/
check status for driver state

if using scsi, maybe your cable not plug properly.

[Mridul Shrivastava]

Try restting the device and check, since its showing as NO_HW its not a driver issue, either cable is not connected prperly or may be there is some hardware issue.

[Andrey Tumanov]

The problem may be with the connections, cable, controller or the drive itself. Try checking the drive and the cable on another system to see if it works.

Dear prash,
please speify which ultrium you are connected to your system.if it having auto termination please check the cable ,other wise check the terminator and scsi cable from server to ultrium drive ,make ensure that it is powering on .you can check in pdc wether it is detecting the drive in there

Hi Prash,

If the OS says NO_HW, it cannot see it.

Check the physical device, could be bad cable, terminator, powered-down.

Check /var/adm/syslog/syslog.log and see if there are errors/error-codes pertaining to the HW as well.

Cheers,

Another possablilty could be:

If you are using a SCSI connection to the Ultrium drive, the speed of the SCSI card may need to be changed to match up the the Ultrium drive.

Do an "ioscan -fnH0/3/1/0" and paste it please.
