Re: EVA 6000 vdisk map to HP-UX device file
This is one of those deals where you will have to at least provide a copy of part of the output and the ioscan.

Re: EVA 6000 vdisk map to HP-UX device file
We have 94 Virtual Disks on one of our servers. Several of them are not currently allocated.
We want to move some of the 94 vdisks to another server, but we want to make sure that the Vdisk is not already allocated.
IE: Zeus_Vdisk015 points to which HP-UX device?

Re: EVA 6000 vdisk map to HP-UX device file
There really isn't a magic trick here.
You may be able to cobble together a script.
ioscan -fn
vgdisplay -v
strings /etc/lvmtab
From this point you will be able to assemble a list of disks that are actually allocated to volume groups, and likely to be in use.
ioscan shows you all available disks, should show all 94. The other commands provide various ways to see what disk is allocated.

Re: EVA 6000 vdisk map to HP-UX device file
Someone mentioned to me we can "unpresent" the virtual disk and then do another ioscan and which ever disk shows No Hardware determines the one-to-one relation.
That's what I really need...Zeus_Vdisk012 is mapped to /dev/rdsk/c8t0d6

Re: EVA 6000 vdisk map to HP-UX device file
If you unpresent a disk which is already used by the system it will be a proble.
as SEP told, you may check the following things,
1. strings /etc/lvmtab
2. verify the same with vgdisplay
3. vxdisklist - any vxvm disk if you are using
4. bdf ( if anyone mounted disk directly, now a days noone use it)
5. swapinfo -tam , if anybody used the full disk as swap
Compare this with Ioscan.
Which OS you are using ? if 11.31
check #ioscan -m dsf
also to find out if there any alternate paths are there
Regards,
Sooraj

Re: EVA 6000 vdisk map to HP-UX device file
probably the best way to identify the vdisks is to use evainfo command.
Hope this helps!

Torsten.

Re: EVA 6000 vdisk map to HP-UX device file
Eva info is the good tool to identify the lun wwn, then you can match it with EVA side. But you are not mentioned the OS version. Here is the link you can download the same tool related to your OS version..

Re: EVA 6000 vdisk map to HP-UX device file
Checking the links.
Sooraj and Torsen...I made a mistake assigning points. Post reply and I will correct. Should be 7.
