It does indeed look like this *might* be a dump issue- but it also could simply be that any single threaded action for dump(8) is going to make for lousy performance. > > > yorp.feral.com > tape_pattern_tester > > tape_pattern_tester: [ -v ] [ -b blksize ] [ -r blocks per file ] [ -n > > number-of-files ] -f no-rewinding-tape-drive > > yorp.feral.com > tape_pattern_tester -v -b 32k -r 1000 -n 5 -f /dev/nsa0 > > .......Rewind Tape > > ........Write Pass > > EOT at File 4 Record 1000 Offset 32768 (163840000 total bytes written) > > Elapsed Seconds: 60; Data Rate: 2.6MB/s > > .......Rewind Tape > > .........Read Pass > > EOT at File 5 Record 0 Offset 0 (163840000 total bytes read) > > Elapsed Seconds: 72: Data Rate: 2.16667MB/s > > Hum... 32KB block size... is that size appropriate for DLTs?

The only way I was ever intending to 'wire' a device name to a WWN in FreeBSD would be to have WWNs export to devfs. The config framework in *NetBSD* might allow for this kind of wiring in their config framework- but I doubt I'd ever spend the time to do this. That is, it's probably worth doing, but the priority of getting it done falls below, say, an IP stack for the ISP driver. > > Assuming this feature is available/coming soon has any discussion occurred > about some mechanism for supporting hot swap of FC devices, without > rebooting, such that the new device shows works with the previous device > name? The 'hot-swap' feature already partially exists in -current. This is code snippet from isp_freebsd.c: case ISPASYNC_PROMENADE: { struct cam_path *tmppath; const char *fmt = "Target %d (Loop 0x%x) Port ID 0x%x " "(role %s) %s\n Port WWN 0x%08x%08x\n Node WWN 0x%08x%08x"; static const char *roles[4] = { "(none)", "Target", "Initiator", "Target/Initiator" }; fcparam *fcp = isp->isp_param; int tgt = *((int *) arg); int is_tgt_mask = (SVC3_TGT_ROLE >> SVC3_ROLE_SHIFT); struct lportdb *lp = &fcp->portdb[tgt]; isp_prt(isp, ISP_LOGINFO, fmt, tgt, lp->loopid, lp->portid, roles[lp->roles & 0x3], (lp->valid)?

But there's another issue here, really. You're talking about replacing a drive. If the WWN stays the same, ISP already guarantees that *while you're still in the same boot session* that the target ID doesn't change. If there's no notification (e.g., via a LIP causing a Port Database or Name Server Database change) that the device has gone (e.g., on a segmented loop), the device, even if it appears at a different Loop or Port ID, will still retain the same target ID. But when you reboot, all bets are off- first come, first assigned, etc. This is where a /dev/wwn/XXXX might be useful. We've tended to not have to try really hard to solve this SAN problem because the preponderance of devices on SANs are disks, and the only time you see a disk that's without a self-identifying volume manager type of label on it is when it's fresh and you're importing it, in which case you don't have any device unit number to preserve as yet. Tapes are indeed a different story. Again, the best bet for this might be WWN aliasing. This bcomes a bit awkward- you'll have a 16 digit hex number and suffixes like you have for tape. I'll put this into my spanking new bugzilla database to remind me to get it done. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message From owner-freebsd-scsi Mon Jul 30 12:14:29 2001 Delivered-To: freebsd-scsi@freebsd.org Received: from smtp8.xs4all.nl (smtp8.xs4all.nl [194.109.127.134]) by hub.freebsd.org (Postfix) with ESMTP id 7DA5A37B401 for ; Mon, 30 Jul 2001 12:14:24 -0700 (PDT) (envelope-from wkb@freebie.xs4all.nl) Received: from freebie.xs4all.nl (freebie.xs4all.nl [213.84.32.253]) by smtp8.xs4all.nl (8.9.3/8.9.3) with ESMTP id VAA08071; Mon, 30 Jul 2001 21:14:22 +0200 (CEST) Received: (from wkb@localhost) by freebie.xs4all.nl (8.11.4/8.11.4) id f6UJEMB01489; Mon, 30 Jul 2001 21:14:22 +0200 (CEST) (envelope-from wkb) Date: Mon, 30 Jul 2001 21:14:21 +0200 From: Wilko Bulte To: Matthew Jacob Cc: scsi@FreeBSD.ORG Subject: Re: DLT 4000 throughput and cstream Message-ID: <20010730211421.A1475@freebie.xs4all.nl> References: <3B630DE0.FC696BC4@progroup.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i In-Reply-To: ; from mjacob@feral.com on Sat, Jul 28, 2001 at 01:11:56PM -0700 X-OS: FreeBSD 4.3-STABLE X-PGP: finger wilko@freebsd.org Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org On Sat, Jul 28, 2001 at 01:11:56PM -0700, Matthew Jacob wrote: > > [ -hardware trimmed- Only one list is needed ] > > > > > KB/t tps MB/s > > > 60.59 22 1.31 > > > 60.59 22 1.31 > > > 61.05 22 1.31 > > > 60.62 22 1.32 > > > 60.59 22 1.31 > > > ... > > This is about half the speed you should expect. Hm, it is about what I get on my DLT4000 drive using dump. Dump just does not keep the tape streaming. I know from experience that the DLT can do much better than this.

Anyone using this controller? Happy with it? They're nothing much to write home about. Ok, but not a great bargain, or a real performance monster.

Ultra/Wide or later), that controller will be a bit of a weak link. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
