Disk shows NO_HW

Hello,

One of the EVA LUNs presented to our UNIX server(HP-UX 11.31) has been detected as failed due to one of hard drives failure. The failed drive has been replaced and LUN has been re-created.

 

The situation on the server is as follows:

 

disk     70  64000/0xfa00/0x25  esdisk   NO_HW       DEVICE       HP      HSV200

                      /dev/disk/disk70   /dev/rdisk/disk70

 

FS /var/opt/ignite is not accesible and cannot be unmounted:

 

vgchange -a n /dev/vgignite

vgchange: Couldn't deactivate volume group "/dev/vgignite":
Device busy

 

rmsf -H 64000/0xfa00/0x25    
Device at 64000/0xfa00/0x25 is busy. Cannot remove.

 

Any help is much appreciated.

Re: Disk shows NO_HW

Locate the document

 

scsimgr

SCSI Management and Diagnostics utility on HP-UX 11i v3

 

and follow the LUN replacement instructions.

 

OR

 

just reboot the server.


Hope this helps!
Regards
Torsten.

Re: Disk shows NO_HW

Thank you for your reply, Torsten.
I went through the document, but there is no scenario there with the disk that shows NO_HW.
I ran scsimgr get_info all_lpt -H 64000/0xfa00/0x25
and the SCSI services internal state = FAILED for all 4 Lun paths.

Re: Disk shows NO_HW

see page 28, chapter

Validating online replacement of devices and SAN reconfigurations

you need to run the

scsimgr replace_wwid

command.

Hope this helps!

Re: Disk shows NO_HW

Thank you , Torsten.

Asked the LUN to be unpresented and presented back. Was able to see the the message in syslog which instance to replace and ran scsimgr replace_wwid.
