If I understand you correctly, you want to share all 4 drives between
the Media servers and the NAS device. Allowing the NAS device to do
local backup and not use the network. If that is correct I am afraid it
is not possible with the Sun NAS device.
See the support.veritas.com web site for the current "Veritas
NetBackup(tm)Network Data Management Protocol (NDMP) Compatibility List
(updated January 29, 2007)" document number 251713. The Sun NAS device
is only supported for Direct attached, remote, and 3-way NDMP, not SSO.
So with the Sun NAS device the only possible solution to use direct
attached tape drive would be to zone the SAN to have at least one tape
drive dedicated to the Sun NAS device. This would however limit you to 3
or less drives for the 2 media servers to use for non-NDMP backups.
Otherwise you could use remote NDMP, but that would require pulling all
the data over the network.
To clarify the reason that some vendors are not supported, there are two
different ways of doing scsi reserve and release. If the vendor does not
support the hard reserve / release that NetBackup uses we cannot assure
the integrity of the data and thus cannot support SSO on that platform.
So far Only these vendors have been certified to support SSO:
EMC Celera in most of the 5.1 and higher DART OS Revisions
ONStore in EverON 1.2.3 and higher
IBM running Data ONTap 7.1.1 and higher
DinoStor running OS 3.6.5
NetApp running 7.1.1 or higher

Ok... Just a point of clarification here...
I was under the assumption that if I had 4 fiber drives in library
shared with 2 media servers via SSO that I could also share one of those
drives with an NDMP NAS, namely a Sun StorEdge 5320. Is this not the
case?
Just to clarify, when it comes NDMP backup time I want the Sun StorEdge
to allocate one of the SSO drives and write its data to it while sending
metadata to one of the media servers. Is that not gonna happen?

Rongsheng,
NDPM and SSO works very similar to normal SSO with NetBackup.
What I would do is configure the Windows and UNIX hosts to share the
drives first, then configure access to the NDMP Host (Celerra NAS), then
finally modify the drives to include the NDMP path to the drives.
You can then set up an NDMP storage Unit, and start backing up.
However I feel the need to advise you that not all versions of all
filers are compatible with SSO, this is mainly due the way reserve and
release are handled in some versions of some manufacturers Filer OS.
Please check the support.veritas.com web site, compatibility list for
NDMP to verify that your Filers OS is compatible.
Thank you,
Mike Heck
