EVA 6000 - OS not seeing new LUNs

[EU-Admins-UNIX]

Hi

I have created and presented some new vDISKs on the EVA6K to an HP-UX11.31 RP7420. but forgot to note which ones I was going to use in which VG.  They were now visible to the OS with sizes, but showing unused in SMH.

I then proceeded to unpresent them and delete them from command view GUI, and now they show unused with zero size.  My plan was to re-create on at a time.  When I create one new vDISK and present, I cannot see it in SMH.  Also, an ioscan -fnCdisk before and after creating this new single vDISK, shows no difference.

Hope this makes sense.

Regards

There is an easier way called "evainfo", this is part of the SSSU download for P6000 /EVA.

However, if you delete a LUN and re-present the same LUN number, the OS will nott allow access until you allow it using the scsimgr replace_wwid command.

Look for

scsimgr

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

page 30.

if a reboot is possible in your case, reboot should resolve it.

if rebooting is not an option, make a note of LUN# being used, and unpresent and re-present the luns through a new LUN # , (select LUN assignment from presentation window) ...this should fix your problem..
