This issue has been solved. See solution.

we have cluster windows 2008 with netbackup

master server and media server are linux with

Windows cluster has drives, which are reserved for customer, they will be maybe used in future

we are not allowed to set drive letters (drives are switchable, so they are on active node now, this is inactive node)

so we cannot use w2koption -backup -ignore_unresolved_volumes

is there any other solution for backup selection all_local_drives?

could you expline why you cannot use w2koption -backup -ignore_unresolved_volumes.

ignore_unresolved_volumesis the one of the better solutions , if you want to to use ALL local Drives.

if not, you need to sepecifically 2 policeys, one for local Drives and another policy for  Cluster Drives as Client Name as Cluster name.

below tech note might give more info

the drives are not for using now

so normally you don't see these drive in windows (hired drives witout drive letters)

i cannot use w2koption, becuase these drives doesn't have letters

PLEASE read through TECH35842 -   link in Nagalla's post.

I always recommend having a minimum of two policies for clusters:

One policy for actual node names that backs up internal drives (e.g. C:\ and Shadow Copy Components).

Another policy for the virtual hostname to backup the clustered data. 

Please read through these sections of the TN: 

a) To backup the cluster nodes

b) To backup the Virtual Servers

 Ignore references to Virtual NetBackup Media Server. if clustered clients are not Media servers as well.
