Wow Johnson !!! is it possible to derive lunid from ioscan output??

[root@mumprod]/opt/IBMsdd/bin# ioscan -fnC disk

Hi All,

Thanks for your replies, storage being used is 3par. As such there is no storage/external tool installed. so used the vxdisk list command and used the formula method to get lun numbers(cxtydz--> (y*8)+z)

[Torsten.]

The formula is good as long as the LUN number is not too high and it is the same cx(dytz) value. With another "x" you need another formula.

LUN Identification command:-
------------------------------------
syminq |grep -i "ABCD"

Where ABCD = 4 digit unique number of disk. It is for EMC

For HP XP Storage .

xpinfo |grep -i "ABCD"


Where ABCD = 4 digit unique number of disk.

Simple command to get LUN details from storage (LUN present on HP UX server) is:

# xpinfo -i

To Recognise only physical disk status:

# ioscan -fnC disk
