These are indications of UNIX/Linux "man" (manual) pages. The (1M) and the (1) are "sections" of man. Typically 1 = User commands and 1M = administrative commands. However, it is somewhat arbitrary as to who defines what as what. For me most NetBackup commands are "administrative" as we don't have "users" doing things with it.
The NetBackup specific man pages are usually in your install directory (mine is /usr/openv) so would be: /usr/openv/netbackup/bin/goodies/man /usr/openv/man /usr/openv/java/man If you do ls in each of those directories you can see which man pages each contains. You can add those directories to your MANPATH variable to be able to read the man pages: e.g. export MANPTH=$MANPTH:/usr/openv/man:/usr/openv/netbackup/bin/goodies/man:/usr/ openv/java/man That allows you to type "man bp" for example and read its man page. For more details type "man man" as the man command itself has a man page. -----Original Message----- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of karthikeyan.sunda...@cognizant.com Sent: Wednesday, July 01, 2009 3:21 AM To: veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] (1M) in Veritas Unix Commands HI, I could find a Attribute like (1M), (1) in the commands of VERITAS UNIX.

I suppose it revolves around how one defines "partitioning the library": Hard partitions or soft (by tape label ranges). We have a Sun/STK SL8500 with ACSLS as the front end and have several (unrelated) Netback Master servers (and media servers) all using the library concurrently.

FYI-- If you use one of the large STK (now Sun) tape silos, you *have* to use ACSLS-- it's not really an "extra". It's part of the silo control system and how any product (e.g., Netbackup, HSM, etc.) requests tape mounts/dismounts. These silos have a Data Path (how your system connects to the back of a tape drive for data transfer) and a Control Path (how your system requests robotic tape-handling actions). A Sun/STK SL8500 can also be hard-partitioned into 4 LSMs (ties a physical group of tape slots with a physical set of drives). At our site, we probably have 10+ separate systems sharing a single SL8500 silo (with a single ACSLS interface). Trivial in Netbackup (just don't tell it about anybody else's tapes). Previous posting is quite correct-- you don't want to have multiple systems "own" any given tape. --- Cris -- Cristopher J.

By having multiple jobs writing to the same tape, the tape doesn't have any idle time to shoe shine your drive. I have 2 tape libraries, both with 12 drives a piece. All 24 drives and 2 robots are presented to my 1 Linux Master, 2 Linux Media, and 3 Tru64 SAN Media servers. All 6 systems see all 24 tapes drives and the robot for each library. The factor that allows me to do this is that my 6 servers all have multipathing support built into the OS. If your Windows server is connected to a SAN, I'm 99% certain you have multipathing in your OS somewhere, either built into the kernel, added via a software pack, or managed by the HBAs on the server. The way I understand SSO, is if you're using anything more complicated than a stand alone tape drive, then you need SSO (I could be totally incorrect here, this is me trying to summarize SSO in 20 words or less). Given the little I know of your SSO configuration, I'd start with going over the way your SAN is zoned with a fine tooth comb. 90% of all the SSO issues I've had with my 2 libraries existed in the SAN itself, not in NetBackup or the libraries. Hope this helps. - Heathe Kyle Yeakley David Turner wrote: > > I have 1 windows master running Netbackup 6.5 with 3 media servers.

However! If those two drives fail - bad tape - bad whatever and are down then that media server has NO tape drives avail. I have 18 tape drives and have zoned all 18 to all of them to all 4 of my media servers. So they use tape drives based on NB's algorithm of which drive to use next kind of evening out the usage some what, and if two drives go down the there are still 16 drives available for the media server to try and find one not busy. ________________________________ From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Donaldson, Mark Sent: Tuesday, June 30, 2009 4:05 PM To: David Turner; veritas-bu@mailman.eng.auburn.edu Cc: Will Tucker Subject: Re: [Veritas-bu] SSO Option for LTO3 drives If a drive is visible to one and only one server because of zoning , then SSO isn't necessary.

I believe the engineers that configured the zoning on the switch dedicated 2 drives per server and dedicate 2 to the Netapp. Did it makes sense to purchase SSO? I was told you should only have 2 LTO3 drives per servers because of "shoe shining" and the servers ability to handle more than 2 drives (Dell 2950's quad cores with 8gig of ram). I am wondering if the switch should be rezoned to make use of SSO or can the zoning have an impact on how SSO should be configured? How can these 2 play together? As you can see I am all confused and would love for someone to explain this in simple terms. thanks -------------- next part -------------- An HTML attachment was scrubbed...

So serverA zoned to all 18 drives. Storage unit is 2 drives at a time. Then serverA still only uses 2 drives at a time out of the 18 that might be available. ________________________________ From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of judy_hinchcli...@administaff.com Sent: Tuesday, June 30, 2009 4:23 PM To: mark.donald...@staples.com; dtur...@manh.com; veritas-bu@mailman.eng.auburn.edu Cc: wtuc...@manh.com Subject: Re: [Veritas-bu] SSO Option for LTO3 drives I agree if you are only zoning each drive to one media server the SSO is not needed. However! If those two drives fail - bad tape - bad whatever and are down then that media server has NO tape drives avail. I have 18 tape drives and have zoned all 18 to all of them to all 4 of my media servers. So they use tape drives based on NB's algorithm of which drive to use next kind of evening out the usage some what, and if two drives go down the there are still 16 drives available for the media server to try and find one not busy. ________________________________ From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Donaldson, Mark Sent: Tuesday, June 30, 2009 4:05 PM To: David Turner; veritas-bu@mailman.eng.auburn.edu Cc: Will Tucker Subject: Re: [Veritas-bu] SSO Option for LTO3 drives If a drive is visible to one and only one server because of zoning , then SSO isn't necessary. SSO is used to share a single drive among multiple media servers. Each server uses it in turn but then releases it after use to be used by a different server. While you may be licensed for SSO, what you're describing won't need it. You could still limit the use of drives by each media server through multiple techniques - storage units "max drive" setting comes to mind - so that only X number of drives are used simultaneously per media server. You could still have it choose that X drives from a shared pool of all your drives. I suspect your servers are more than capable of keeping two drives busy (subject to throttling introduced by your back-end SAN & HBA speeds). Your storage guys are, IMO, being too conservative.

I have Storagetek/Sun SL8500 with 8 LTO3 tape drives (2 drives are dedicated via NDMP to a Netapp 3050). All drives are connected via FC to brocade etc. we have the Shared storage option but I don't think it's working properly. How can I verify that its working?
