NO_HW state on ioscan output

[Rosli Ahmad]

Hi,
I've just attached a DLT8000 tape drive on my HP9000 D-class server but the ioscan -kfnC tape state="HO_HW". My question is how to activate this tape drive. Thank you.

NO_HW means the device was connected and powered up - HP-UX could see it, but now it cant. So the connection has been lost. Check power/scsi cables. Once youve checked it and found the problem do the ioscan again and see if it comes back as CLAIMED, then you can use it.

Well if you were to refer to your previous post on hte DLT800 issue, you would have read quite a few bits of advice on htis.
I gather you have just attached the drive to hte system without a reboot, so what happens if you do ioscan or ioscan -f?
Also, is it at the same address it used to be, or has that changed?
You MAY be forced to do a reboot after all.

Hi,
First & foremost I don't have the root access, it's under sudo. I can issue ioscan -kfnC, but 'ioscan' alone gave me '/dev/config - permission denied'.
As for the address, I believe it remains as it was before.
Pls. don't tell me I need to reboot the server, they'll definitely kill me.

thx.

without root access, reboot

Hi,

Hardware changes are defintely root-jobs. So either rebooting will perform an ioscan for you, or user root has to do this. Sorry.

Good luck
