How can I match/map a 'host' in CAM to a real host? How can you explain these words that sounds like a real host from Sun manual?
"A host represents a data host, which is a computer that is attached to the storage array and generates data to be saved in a storage array. The data host sends data to the storage array using a Fibre Channel (FC) connection. A host must have one or more associated initiators to enable you to map volumes to the host."
Thanks.

The T2000... (15 Replies)

In Sun manuals, I didn't find how to backup Sun StorageTek Common Array Manager's configuration. Is there a way to do it like backing up Brocade switch configuration? CAM is under Solaris 10.

Bought a Sun StorageTek 2540 SAN array a few years ago from a company that was going out of business. When we first set it up, we were able to get all the software (Common Array Manager) and firmware directly from Sun.
We just upgraded the drives, but the array is too large for the firmware. Now... (6 Replies)
