Regarding Server free backup

[Satish Kumar_5]

Dear Experts,

I have a MSA 1000 with embedded MSA SAN Switch. 2 dl 380 Server and 1 HP MSL 6030 Tape library with NSR is connected to this SAN switch.We want to do a Server free backup. The backup s/w used is CA Arcserv 11.1. While doing the same its giving error. As per CA technical support, through the SAN switch you should be able to see and access the drives in the disk array if these drives have LUN # assigned to it. We have created 3 LUNS with RAID5 and we are able to access them from our Server.

We dont have any zoning in SAN switch. As per HP also something need to be done in SAN switch.they are not telling what it is. i read through SAN switch guide and not able to find any helpfull information.Please help.I know you guys can help as always.

Thanks in Advance.

Try to do proper zoning.

I.e. zone together each host-facing port on a switch with appropriate storage-array-facing port. Then zone tape-library-facing port with all storage-array-facing ports.

It should work.

Hi,

Thanks for your time.Do you think zoning will solve.The 2 Server are in cluster and they need to access same LUNS accross.

I am revisiting this in my mind & this is more complicated than that.

Basic question: where is your CA backup server installed?

Hi,

CA is installed in 1 of 2 Server which are also connected to the same SAN switch.

Thanks for ur help.

OK, so it's probably not the best config - you should really consider having a dedicated backup server.

In your current config your zones should looks as follows:
- Zone 1: Host1, appropriate storage port(s), Tape Library
- Zone 2: Host2, appropriate storage port(s), Tape Library

One more thing: did you check with CA guys whether your config is supported or not? I mean having backup server & client server on the same machine?

Hi,

As per CA our h/w is supported. This is what a CA specialist ask from me:

"After consulting with the SAN specialist here, according to them, through the SAN switch you should be able to see and access the drives in the disk array if these drives have LUN # assigned to it."

Thanks for your time and help buddy.

One more thing,I have a setting in NSR of tape library called "ACTIVE FABRIC SETUP". this got a parameter called ServerFree BAckup which is set to disabled. What this means? Is there any way to enable the same?
