Sorry, I misread that. You are correct. Disabling Windows automount is highly
recommended.

This seems contrary to best practice .. if you don't instruct Windows to not
automatically mount new volumes, and zone in the ESX datastores/VMware LUNs ..
Windows will try to mount those LUNs upon presentation, and therefore damage
live production VMs
Yes - don't try to mount/format/repartition VMware LUNs from your Windows Media
Server - but you should be running "automount disable" before presenting said
LUNs!
Kind Regards,

Hi Adrian. Answers inline:
>> - Do we have to run the diskpart command (automount disabled & automount
>> scrub) before mapping the VMWare storage to Windows Backup Host?
NO! Do not do this. You need to do nothing to the LUN's from the Windows
side. If you partition or otherwise modify the VMware LUN from the Windows
backup system you will destroy all of the VM's on that LUN.
>> - What entry should be defined in NetBackup Administration credentials?
You just need to define the credentials of the vCenter server. You do not need
to add the credentials for each ESX server.
>> The question is, to run VMWare backup over SAN, do we have to define the
>> ESX server in Credentials?
No. I suspect that the problem that you have is that the SAN based LUN's are
not properly shared with the Windows backup host or they are the wrong LUN's.
When the LUN's are correctly shared, they will show up in the Windows disk
manager as a "Healthy, unknown partition". The exact wording for this might
change depending on the version of Windows you are running. If you see the
LUN's in the Windows disk manager and backups still fail it could be a
permissions issue (permissions are defined on the vCenter server) or the wrong
LUN's are shared. Because network (NBD) backups are successful, the VADP
process is working but most likely the SAN based LUN's are not shared correctly.
The required vCenter permissions are defined here:

Dear Simon,
We use NetBackup 7.1, do we still need to get the latest NBU Update Pack?
The re-scan disk results in nothing.
I'm not sure whether the configuration of our SAN and NetBackup is complete or
not.
That's why I want to ask a few questions regarding this VMWare backup over SAN:
- Do we have to run the diskpart command (automount disabled & automount
scrub) before mapping the VMWare storage to Windows Backup Host?
- What entry should be defined in NetBackup Administration Console | Media &
Device Management | Credentials | Virtual Machine Servers?
First, we just define only one VMWare VCenter and the VMWare backup runs
successfully over LAN only.
When we have a failure running VMWare backup over SAN, then we tried to
define the two ESX server we have, but we have this error message:
"Host is invalid"
Then, we try to enter the IP Address of the ESX and both of the IP address of
the ESX server can be defined here.
The question is, to run VMWare backup over SAN, do we have to define the ESX
server in Credentials?
Thank you for helping.

Ok so you see it ... but does Disk Management show anything after you do a
re-scan disks?
And its definetely presented correctly (your VM Backup Host) on the SAN?
Also ... and I said this last time... did you get the latest NBU VMware Update
Pack, because this fixed many problems for me, especially doing via the SAN as
it was horrible speeds.
I was on 7.0.1
Take it you rebooted?

Subject: [Veritas-bu] Problem of VMWare ESX Backup via SAN
Dear all,
I have another problem related to the previous problem which is a VMWare ESXi
Backup Problem.
The VMWare ESX backup has already been successful through LAN backup, but it's
still failed if I use SAN backup/transfer type.
Here is the description & facts of my problem...
DESCRIPTION OF PROBLEM
VMWare ESX backup is failed if it's set to use SAN, but is successful if it's
set to use LAN.
FACTS & FIGURES
- Master Server:
OS: IBM AIX (oslevel 5300-12-04-1119)
NetBackup 7.1
- Media Server & Veritas Backup Host:
OS: Windows 2003 x64
NetBackup 7.1
- Client/Machine to be backed up:
VMWare ESXi 4.1
- The storage unit for the backup host has already been set up.
- I've already added the VMWare Virtual Center into the Credentials | Virtual
Machine Servers (from Java Administration Console).
- The windows Veritas Backup Host is a media server as well and I have linked
it to the VMWare storage and tape backup drive through the SAN switch.
- I've already disabled the automount using diskpart command, so that the
storage will not be initilized and formatted by Windows.
- The VMWare storage can only be seen from Device Manager and not from Disk
Management.
Please help me solve this problem.
Thank you in advanced.
