Re: Disk failure

Try this.
ioscan o/p
==========
disk 17 64000/0xfa00/0xa esdisk CLAIMED DEVICE TEAC DV-28E-N
/dev/disk/disk17 /dev/rdisk/disk17

# ioscan -funNCdisk |grep -i "64000/0xfa00/0xa"
disk 17 64000/0xfa00/0xa esdisk CLAIMED DEVICE TEAC DV-28E-N

See the 17 means /dev/disk/disk17

Re: Disk failure

Hi Rahul,


This is Vitual Hardware Addressing in 11.31,

One of the External Storage LUN has some issue!


Please checking this link:

http://docstore.mik.ua/manuals/hp-ux/en/5992-4580/ch03s03.html

Search for "virtual hardware address"

You can decode the Disk at hardware path 64000/0xfa00/0x100 .

HTH,

Re: Disk failure

Hi,

This is a feature that is inbuilt with the agile addressing method where the virtual root node and virtual bus are universal. That is why you will always see 64000 and 0xfa00 for all virtualized hardware addresses. The only thing that changes is the last field which is generated by the kernel (0x100).

If you want to see the corresponding legacy or agile "lunpath" hardware path execute

ioscan -m hwpath

Re: Disk failure

Here is an example:

$ ioscan -m hwpath
Lun H/W Path Lunpath H/W Path Legacy H/W Path
====================================================================
64000/0xfa00/0x0
0/4/1/0.0x5000c50001234567.0x0 0/4/1/0.0.0.1.0



Use also

# ioscan -fN

or

# ioscan -fnkNCdisk

Hope this helps!
Regards
Torsten.
