Disks not visible in HP-UX 11iv3

[suvy12]

Our Storage team has assigned 58 Luns from Hiatachi Box to HP-UX 11iv3 . But the problem is that these disks are not visible in the OS even i run the insf . According to storage team there is not any problem from their side but disks are not showing in ioscan output.
Can anyone help me in sort out this problem.

Did you run "ioscan"?


Ask the storage team if zoning is correct and if the LUNs are presented in "hp-ux" mode!

Yes i ran the ioscan.
And accoding to storage team Zoning is correct.
Is there any other way in HP-UX 11iv3 than the 11iv2

It is different if you have already a LUN assigned, you unassign this LUN and assign a different LUN with the same number.

Then you need to work with scsimgr.


But if you don't do this, "ioscan" should be enough.

If zoning is correct and wwn is right then ioscan/insf should show you the disks.

Reboot and see if it helps,
Sounds strange, may be worth trying,

Check your HBA' that are in use...

fcmsutil /dev/fcd<#>

Make sure that it comes back and shows:
Driver state=ONLINE

If it shows Disabled or No_Light then you have a problem with the connection from the host.

Not sure if your hard or soft zoned. In fact, use that terminology when you go back and talk to your SAN folks.
The first line N_Port Node WWN would be the # used for hard zoning. But I'm banking they are soft zoned, so the second line N_Port Port WWN is for soft.
Write those numbers down for both and ask them to confirm them for you.

FYI - hard zoning is done for greater security, but makes changing anything more difficult-only large security required shops tend to use this; soft zoning is what most shops use. Knowing this will keep the SAN folks on their toes!

If you're dual fabrics you'll have to do this for each used HBA.

Just a thought,

One more thing, not sure if anyone mentioned.

Did the remember to map and mask the disk to the host after they zoned them?

How are you running 'ioscan'? If you are running something like 'ioscan -fnkC disk' then you wont see the new disks. Likely you have done this type of work before and this is not the problem here, but... Just to check, be sure you are not using the -k option so that a new hardware scan is performed.
