3rd party drives for Netapp F820 (fwd)
by Daniel Feenberg 08 Aug '01

08 Aug '01

Sorry if this is a FAQ, but I am new to the list and can't seem to browse http://teaparty.mathworks.com:1999/toasters. We have an F820 filer from Network Appliance with a single DS14 drive shelf. The shelf came with 14 cartriges, of which 7 had 36 gigabyte ST336704FC drives, and 7 were empty. We would like to fill the empty drive cartridges with Seagate ST373405FC (72 gigabyte) drives, but the F820 complains "Drive not supported" when we insert the drives in the slots. Is the error message because we didn't buy the drive from Netapp, didn't buy the right drives, or some firmware issue, or do we just need to update the F820 OS software? Does anyone have experience with using non-Netapp drives in an F820? We have heard that it works, but this is our first attempt. Daniel Feenberg feenberg(a)nber.org

RE: qpopper file locks
by Sims, Aaron 07 Aug '01

You don't mention whether or not you'll have more than one HP-UX system accessing the mail spool. If it's just one, then no problem, stop reading here. If more than one system can access the same mailbox (i.e. load balancing), read on. There are two mailbox formats commonly used. One is 'mbox' the other is 'maildir'. 'mbox' format mailboxes are the most common. They use one file for multiple messages. File locking is always an issue with this format. 'maildir' format is one file per message. This format is generally headache-free in terms of file locking. My experience is that relying on lockd for file locking works 99.9...% of the time. Your milage can and will vary here. Not all NFS clients are made the same. Some UNIX vendors have better NFS and NLM (Network Lock Manager) clients than others. While I don't have direct experience with HP-UX, in small environments, lockd should work fine. (Although in a past life, I've run a F630 cluster with at least 8 Solaris based clients and 250,000 mailboxes relying on lockd with no problems.) If you run into problems, then you should convert to the maildir format. This will require that you patch or change your local delivery agent (the program that sendmail calls to actually write the email to a file, probably mail.local) and your qpopper.

qpopper file locks
by Todd Watson 07 Aug '01

My apologies if this question has been hashed over before on the list, but the archives seem inaccessible at the moment. We are planning on migrating our mail spool files from an HP-UX server to our 740 filer and then mounting them back via NFS. This HP system runs sendmail and pop (qpopper specifically). We are concerned about file-locking issues which may arise or any other "gotchas" that we should be aware of. Thanks! Todd -- Todd K.

If you need support for LVD devices, P/N X2023B-C is an LVD SCSI backup adapter for tape. Check the Sysconfig guide for slots and supported tape drives: http://now.netapp.com/NOW/knowledge/docs/hardware/syscfg/scdot611/index.htm Joe Luchtenberg Dataline, Inc. 757-858-0600 757-285-1223 (mobile) 757-858-0606 (fax) joe.luchtenberg(a)data-line.com www.data-line.com > -----Original Message----- > From: Jim Davis [mailto:jdavis@cs.arizona.edu] > Sent: Tuesday, August 07, 2001 12:31 PM > To: > Subject: Re: HP surestore dlt1 > > > Thanks to the people who reminded me the onboard adapter > really is for HVD > devices, not LVD devices.

Direct attaching SCSI tape drives to 760's
by Paul Letta 07 Aug '01

07 Aug '01

Does anybody have any comments in regard to direct attaching SCSI drives 760's ? My concern is what happens when the drives fail ? I seem to have a drive failure rate of 3 or 4 a year. Currently I do not direct attach, so replacing them is no problem. But what happens to the filers when you remove a SCSI tape device hot ? Can you reattach a new one without rebooting the filer ? I do not think my environment would stand for a filer reboot each time a tape drive fails, but I really do not want to live with the 4MB/Sec I get for backups over the network now. Any thoughts? Thanks, Paul

RE: Veritas b/u not clearing archive bit on NetApp volume
by Adrian Phillips 03 Aug '01

03 Aug '01

Hello again all; Just an update to this issue, that I've recently discovered. I've found that the archive bit does not get cleared if the account used for backup does not have access (NTFS permissions) to the file. It will back it up, but not clear the archive bit. Our user's home folders are all on C:, so that is why I thought it was drive specific. The backup account is in the local Backup Operators group, and is also a member of the Domain Admins group. If anyone has seen this behavior before and has any thoughts, please let me know. Thanks again for your time and help. Regards, -Adrian -----Original Message----- From: Adrian Phillips Sent: Tuesday, July 31, 2001 4:30 PM To: 'toasters(a)mathworks.com' Subject: Veritas b/u not clearing archive bit on NetApp volume Hello List; We have an F760 running CIFS, with ONTAP 6.0.1R3. "C:" is mapped to vol0, and "D:" to vol1. We use Veritas BackupExec 8.5 over the network to connect to and back up the data/shares on these NTFS volumes. What is very odd (and I nor Netapp can seem to figure out thus far) is that the archive bit for files on C: do not get reset after full or incremental backups. Meanwhile, through the same backup jobs, the archive bit on files on drive D: DOES get properly cleared after being backed up. Because the archive bit is not being cleared on C:, our incremental backups are very large, and running well into the work day. I can't seem to find any differences in the volumes, other than vol0/C: is the root volume and uses 9GB drives, compared to vol1/D:'s 36GB drives. Regards, -Adrian
