Re: [Veritas-bu] drives going down on media servers
Hi Blaine, I have been looking to try and solve this problem for two sites that I'm working with right now and we're not having much luck either. In my travels I've talked to a few folks that have seen this External Event issue caused by monitoring software. One client in particular found that one of Sun's monitoring tools was sending out scsi inquiries and causing the external event rewinds. I also ran across a post on this mailing list that documents about 30 such applications that have been known to cause this type of behaviour. Try searching this list for external event. If a get a chance, I'll try and dig it up and send you the post I'm thinking of. Through the course of my research I've basically found that two things are trying to communicate with the drive and most folks check out the data path (hba's, switches, bridges,...) to look for problems. Maybe the upgrade stepped on some scsi reservation setting. If I find anything else, I'll post to the list... Blaine Robison wrote: I am having a similar issue.

[Veritas-bu] win2k DC restoration
Hi, I'm doing to DR testing. I have a unix master and i'd like to restore the BMR boot/win2k domain controller. In past versions of windows, I have installed windows to c:\winnt.dr and then restored the server and set the boot.ini to boot from c:\winnt With win2k, i can restore the system state, so if i want to restore my domain controller, can i install windows to winnt and then restore the c: and system state to get the server back?

RE: [Veritas-bu] win2k DC restoration
Title: Message In restoring a DC the steps are very straight foward but slightly different from a DR restore of a member server 1. Load the correct version of windows (standard, enterprise, whatever) and make it a member of a workgroup with the same name as the domain 2. Create the disk layout (C, D, E, etc of appropriate sizes) 3. Load NBU agent 4. Reboot the server and on reboot F8 the system and choose the DOMAIN CONTROLLER RESTORE MODE 5.

Re: [Veritas-bu] drives going down on media servers
Unbelievably i have seen this yesterday as a windows guy asked me if i knew about it seeing as i support Netbackup on solaris. The fix he got which worked was to disable the Removable storage manager service. The errors are no more. That was on a windows 2003 setup with netbackmup 5.1 mp4 Roger Dombrowski wrote: Hi Blaine, I have been looking to try and solve this problem for two sites that I'm working with right now and we're not having much luck either.

[Veritas-bu] Master and Media HW and OS..
Hi, We run all our master and media servers on HP PA-RISC server and HP-UX as OS. These servers cost a lot, not only to buy, but also in maintenance What do you guys think about going from the above to powerful INTEL server with linux as OS instead in a datacenter environment? We have about 200 clients and (all full is about ~15TB, never at one time though) to backup at one of our sites. Anyone using this type of solution in DC env`s? Recommendations??

RE: [Veritas-bu] Master and Media HW and OS..
I would not recommend Linux for Netbackup environment,simply because it cannot be restored on to dissimilar hardware in DR like scenario , there are other reasons as well . (I have a list ) .. On the cost , I don`t know about HP RISC but IBM`s P-series (RISC) hardware which runs AIX is cheaper than Intel hardware(surprised??) . I am working on a business case to move oracle running on Intel/Linux off to to AIX,So comparing Pserise vs... Intel hardware (price,performance ,DR , LVM ,etc..)I know thepricing/quotes and other details about the hardware. send me an email offline if you need to know more about it . Our master and media is running on IBM pserise servers P550 . http://www-03.ibm.com/systems/p/ Shekhar Dhotre ICTStorage Engineering. v 404.846.7483 | f 404.848.1077 [EMAIL PROTECTED]48 Perimeter Center East | Atlanta, GA 30346 "Mistakes are a fact of life.

RE: [Veritas-bu] Master and Media HW and OS..
I dont know anything about Linux, but in our installation I use Windows 2003 on my combined master/media server. The server is a Dell 2850, 2 x 3,6 Ghz HT Xeon CPUs. I use 2 Emulex LP1 HBAs to give me access to the SAN (2 connections to disk and 2 to tapes) and one Qlogic HBA to connect to the library. Connection to our LAN is at the moment 2 Gbit/s The server feeds 4 STK9940B drives Except for the LAN connection I really dont have any problems with performance. Daily backup volume is around 2,5 3,0 TB from 80-100 servers running anything from NT 4.0 to Windows 2003, Exchange, SQL, SPS, BizTalk and God knows what. I even have a bunch of VMware ESX servers. After I migrate to NBU 6.0 I will add one extra media server and share the drives using SSO. Windows isnt the best operatingsystem for have I/O load, but I dont want to migrate to Solaris because of the extra cost and also dont want to use Linux because I am the only one who knows anything about Linux in our shop. And we have to pay a lot more for a RedHat ES server licens then what we pay for a Windows licens (NBU cost is the same for Windows and Linux) From all what I know about performance on an Intel box (or AMD) you would get a decent performance out of any box now-a-days for NBU use. I would go for a 4 CPU box using Xeon processors with 4 GB ram, some good HBAs and some good NICs if I had the money. But a 2 processor box as the one I use can feed 4 drives in my installation without any real problem. Even if my info is from Windows, I hope you can use it. /johnny From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hampus Lind Sent: 24. januar 2006 20:05 To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Master and Media HW and OS..

RE: [Veritas-bu] Master and Media HW and OS..
Johnny, Can't say I share the same opinion regarding issues with Linux running asmedia or masterservers ina NetBackup environment. I've been using Linux (SLES 8/9) media servers in a SSO environment with ACSLS for the better part of a year and a half and haven't had any major issues. Sure, setting it up was challenging as there wasn't definitive documentation at the time. My media servers are a 2x 3.4 MHz (multi threaded) usingeither Intel/AMD with 4 Gb of Ram driving 4 FC LTO II tapes drives (thru QLogic HBA's) with two 1 Gb NIC portsbonded together.
