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 Thank you, Mike Heck CFT -----Original Message----- From: Martin, Jonathan (Contractor) [mailto:[EMAIL PROTECTED] Sent: Thursday, April 26, 2007 2:08 PM To: Mike Heck; veritas-bu@mailman.eng.auburn.edu Subject: 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? -Jonathan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Heck Sent: Thursday, April 26, 2007 1:56 PM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] NDMP and SSO in NetBackup 6.0 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.
