Hi,

Read this topic please:

You need to run 'ioscan -fn' . Then 'insf -C disk' to see the new DSF . If you are in doubt that which DSF is which CU:LDEV on the disk array, then 'xpinfo' (if the storage is XP) or 'evainfo' might help you.

cheers

If you run ioscan you will find the new disks without device files. Then you need to run insf, but you already know what disks are new.

Depending on the type of array you may also use tools like evainfo, xpinfo, etc ...

After running insf -eCdisk, you can simply list the new device files:

ll -rt /dev/dsk

The new device files are at the bottom of the list.
