Which network ? SAN or Ethernet you do not want to use ?
If the drives are SAN attached and you are using them right now then you
are using network ( SAN ) already anyway.
If you are talking about your TCP/IP network then no worries - only the
metadata is transmited over TCP/IP or commands and status to be exact.
Implementing NDMP will not change your backup traffic flow.
1) Please check previous postings - this was covered just few days back. A
memeber of this list, working for Symantec gave a detailed and specific
answer to NDMP sharing question.
http://www.mail-archive.com/veritas-bu at mailman.eng.auburn.edu/ is a good
WEB archive to use for searches.
2) between the filers ? Using NDMP ? That'd be a 3-way NDMP backup I
beleive. NBU master gives goahead to filer1.
Filer1 dumps to filer2 attached drives. But note (!) - you'll be sending
the backup traffic over the network between 2 filers.

Re: [Veritas-bu] NDMP and SSO in NetBackup 6.0 [NC]
Hello,
I use direct attached tape drives ( through a SAN ) to
backup my filers . I don't use remote NDMP nor 3-way NDMP becaus I don't
want to use the network for backup or restore traffics.
I have 2 questions:
1) It seems that for NetApp filers we have the
possibility to share "filers direct attached tape drives" with media
servers , but the DataOntap version needs to be at least at 7.1.1 version.
Because, my filers are only at 7.04P10 version until now, I can't share
those direct attached tape drives. Is it exact ??
2) If I am in 7.1.1 DataOntap version, will I be able to
share tape drives between 2 filers ??
Thanks .
Gilles.

Jonathan,
I hate to contradict you, however the most current support documentation
shows that the SUN StoreEdge Filers are not supported for SSO via direct
attached drives.
The Sun StorEdge NAS Systems are only supported via Remote NDMP, 3-way
NDMP and in the case of the 4.20M0 OS direct attached NDMP backups.
Nowhere does it list SSO. I have double checked this with the Symantec
testing team as well as with Product Management.
Symantec is constantly working with Vendors to get products certified,
as they are certified the compatibility list is updated. The
compatibility lists are your best source of information, as these are
constantly updated.
The 4.20 version of Sun StorEdge OS currently does not support SSO on
Direct attracted drives. If you were provided with information from
Symantec that it is supported in this way, please contact me off list
with the case number you opened to obtain this information.
Thank You

Original message thread:
I've got confirmation from both SUN and Symantec that The Sun StorEdge
5320 running 4.20 M0 will allow SSO both via Remote NDMP (thru the Media
Server) and Direct Attached. I'm still a bit sceptical, because it
hasn't worked yet, but I've got a fair amount of confidence that when
Sun & Symantec say something works, it will. I'll have it up and
running next week and I'll confirm one way or another.

Why not ?
STK loves NT ... I'm sure it is a Dell box with Enginio controllers ...
If you want to use shared ( SSO ) drives - confirm with STK/SUN if the
NDMP version it runs supports SCSI Reserve/Release and of course as was
mentioned yearlier today, NetBackup have to be version 6.
Regards.

Re: [Veritas-bu] NDMP and SSO in NetBackup 6.0
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
