EVA4000 single path to disk

I have an EVA4000 with windows hosts attached. Some boot from SAN and others are local boot. I have been working on Microsoft ASR process for image restore of the C drives, but in order to do this I need to have a single path to the disk. Is there a way to create a single path to a disk using the EVA? I know I can re-zone the swithes, but I would rather have a way to do it at the EVA LUN presentation. We have an old HSG80 and I was able to do it on their LUN using connections, but I haven't found a way to do it on the EVA.

Thanks,

Howard

Re: EVA4000 single path to disk

Hi,

with the EVA I don't think it's possible. It does not have a connection list like the HSG80 does, where you had separate connection names for each port/HBA combination. Zoning is the easiest way to do it. Changing the zoning requires about 1 minute with the command line.

zoneremove "zonename", "EVA_Port"
cfgsave
cfgenable "cfgname"

On the 2nd fabric you would remove both EVA ports from the zone.
This assumes you have Brocade switches (B-Series)
Then use the zoneadd command to add the paths back when you are finished.

Re: EVA4000 single path to disk

You have to do it via zoning, you cannot present just one path from the EVA.
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: EVA4000 single path to disk

Thanks for the replies. Do you know of a way to load a multipath driver during an Windows ASR recovery? I'm trying to get a image that can be restored quickly without having to re-zone.

In chase I forgot to mention I'm using Integrity servers.

Thanks,

Howard
