Add LUN from EVA and SecurePath

[UNIXGRUPPEN]

I've got 2 N4000 running HPUX 11.0,MC/ServiceGuard and SecurePath 3.0D and an EVA5000.

Now I'm about to present some new LUNs to the cluster (both nodes) and I'm wondering which is the proper way to do it.

Present the LUNs, and then on the first node:

# ioscan -f
# spmgr update
# kmadmin -L swspData
# config -M swspData -u
# spmgr update (making it persistant ?)

Then start making volumegroups and so on...

Is this the right way to do it ?

Since it's a cluster it's important the the devices names/numbers are the same across both nodes.
Is there a possibility that SecurePath/HPUX will name the devices diffrently if repeating the same procedure on both nodes ?

TIA,
Johan

Hi,

Your procedure is OK.
You also can use the commando /etc/ionit (with option -f) to customise the devicefiles from the LUN before secure path is started

Just wanted to add that the LUNs will be added during full production on these machines, so I can't reboot or shutdown SecurePath.

Hm.. on my 11i systems running SecurePath 3.0D.. all we do is "ioscan;insf -e". No more kernel mods and no more spmgr update.

I suppose there is a difference in behaviour between SecurePath 3.0D on 11i and 11.0?

I agree with Nelson, it might be a difference in 11.0 to 11.i. But 3.0D the spmgr update command is gone. 3.0A you had to spmgr update and kml (I don't recall the other 2 commands you need to do after, but it does tell you).

Usually like he stated.
1) Zone switch
2) Discover host if not discovered
3) Create a vdisk
4) Present to host
5) ioscan -fnCdisk to see if it's there.
6) insf -H Hardwarepath
7) spmgr display should show it right away.
8) Create volume group and lvols.
