ALLOCATING IBM STORAGE SPACE TO HP-UX SERVER

[VICTOR HUGO HERRERA]

Hi.

I need to allocate some disk space from an IBM Total Storage ESS 2105-800 to a HP N4000 server, running HP-UX 11.11.

The space's already been assigned. What do I have to do on the server side?

Thanks.

1) # ioscan -fn

This will create hardware path entries

2) # insf -v -e

This will create the device files

Once you've done the above you can then create or extend your volume groups, vgcreate or vgextend, and then create or extend your logical volumes, lvcreate or lvextend.

Hi Victor.

We use the same IBM storage array here. The setup process is really no different than any other storage. Once you identify the hardware paths with "ioscan -fnC disk", you simply run insf, pvcreate, vgcreate, lvcreate, etc..

Here's the output from an ioscan on our system.

(saifprod)/> ioscan -fnC disk
