Hello Every body!!
Once again I am trying to solve a problem with vmware backup. The enviroment is as follow.
The master server is running on Redhat
Netbackup version is 7.5.0.6
I have 9 ESXs servers that share 15 Storage LUNs. Those LUNs are mapped to every ESX via 4 paths.
The Backup Host we are using is the Master Server, so it has been mapped to the 15 LUNs vmware datastore via the same number of paths (four)
When i try to run backups i got the following error number: Error bpbrm (pid=6462) from client XXX: ERR - Error opening the snapshot disks using given transport mode: Status 23
Because in the NetBackup-7x-in-virtual-environments_Sept_9_2014_update (http://www.symantec.com/connect/forums/linux-vmwar...) i found that for a Linux backup host that is not a NetBackup appliance, NetBackup for VMware is unable to support DMP. I have mounted a VMware Workstation laboratory as the same production enviroment to verify and identify the root cause of the problem. So, on the lab i have zonned and mapped the ESX datastore from two different paths over iscsi on the master server running on RedHat 6.3, when i run the backup it works.
The next step to solve the problem is trying to map the vmware datastore luns using single path to the master server but i have been asked to be sure doing so the problem is going to be solved.
Best Regards
