vmware backup through SAN issue

Created: 05 Jan 2013

Hi,

I need help on this issue.

I configured vmware backup through SAN, as below url

https://www-secure.symantec.com/connect/articles/n...

Master server (windows 2008) Netbackup version 7.1.0.4

Media server  (windows 2008) Netbackup version 7.1.0.4

Virtual machine (windows 2008)

 

Configured media server as vmware backup host,

Media server, ESX server and datastore are connected with SAN,

Media server and master server are connected with LAN.

ESX server, master server and media server are connected with  LAN

I configured policy with flash backup windows type with snapshot option with VMware backup host  (media server), in the snapshot option, I selected transfer type as Try SAN and NBD

Then I restarted test backup, backup was completed successfully with 10 MB/ sec, in backup job details, it is showing as Transport type as LAN.

So, once again , I reconfigured zoning between media server, ESX server and datastore,  I selected transfer type as Try LAN and NBD, I restarted test backup, backup was completed successfully with 35MB/sec, but in the backup job details, Transport type is showing as LAN, but speed is 3 times more compare to previous test backup,

Maybe it is using SAN, but Iam not sure, can anyone help me to fix this issue, whether backup job is running through SAN or LAN, because, for FT media server, backup job´s Transport will show as FT, but in VMWare via SAN, it will show as SAN as Transport or ? I don’t have any idea.

 

Note : I tried backup with transfer type as only SAN, but it is getting fail as below error, ERR - Error opening the snapshot disks using given transport mode: Status 23, could not send server status message file read failed(13),

Maybe this issue due to LAN connection between master server and media server, Iam not sure, guide me.
