new san disks

[SM_3]

Apologies if this basic question has already been covered.
I've just done a quick search and found emc data migrations.
im rusty on hp-ux and would like to know how to attach a hp-ux server to new san disks
#ioscan
#insf

do I need to update any configuration files ?

thanks

If your HPUX server is already zoned to the SAN then:

1. Map your disk down each FA
2. Mask your disk to the HPUX host.

If your HPUX server is NOT zoned, then you must Zone it first then map and mask.

Once masking is done, then for EMC I run:
symcfg discover
symmask -sid xxx refresh -nop
ioscan -fnC disk > ioscan.disk
insf -e

...It sometimes takes a few for the c-t-d- to show up. So relax, get your coffee and if you don't see the new disks when you run symdev list...just repeat from symcfg discover.

Sorry, forgot to mention:

If you have PowerPath then don't forget to run

powermt check (just to be sure all is good)

powermt config
powermt save

thanks Rita

no config files to update ?

Nope, this isn't Slowaris or Linux... HP-UX will just see the disks after ioscan/insf as long as the LUN presentation and zoning have been done correctly.

Of course there's more to do to put a filesystem or the likes on these LUNs, but I don't think thats what you're asking...

If your running PowerPath (EMC load balancing software) then those commands are used for that. If your not then just ignore the powermt commands.

And you do have a 'config' file of sorts in EMC. You have the symapi_db and you have all sorts of files that are sort of config files EGF,MHR,MGA, etc. that are part of the EMC software.
But....that's an EMC thing, and this is the HP ITRC Forums..
