FDMI reporting with qla2xxx driver on Linux
by Momonth 09 Dec '16

09 Dec '16

Hi, I recently noticed that qla2xxx (Qlogic HBAs) driver on Linux is capable of reporting FDMI. By default it sends "Linux-default", and I'm failing to see how to change it to actual host name as it becomes way more handy then =) Any ideas? Cheers, Vladimir

yeah it's supported per hardware universe gear isn't on support because money i could upgrade it, i'm just not going to, without support - had too many upgrades go sideways in the past, requiring intervention from support On Tue, Oct 25, 2016 at 10:55 AM, gene <genec220(a)verizon.net> wrote: > Then it is very possible that the gear isn’t supported by your older ONTAP > version.

sas.adapter.debug messages
by Mike Thompson 25 Oct '16

25 Oct '16

Hey all, Recently hooked up a ton of DS2246 w 900g drives to some 6080s and 6280s running (ancient) cDOT 8.0.5, and am seeing a lot of sas.adapter.debug messages when the aggregates in question are under heavy write load. Seeing this on multiple filers, multiple adapters, so I'm guessing it's a bug of some sort, which was likely fixed years ago? These don't appear to be impacting performance as far as I can tell, but I'm not certain (gear was just onlined, and using this as staging area for … [View More]shuffling lots of volumes around). Are these particularly evil? Can't find much online about them, but they don't look very appealing: Oct 24 18:17:47 filer1a pmcsas_intrd_1: sas.adapter.debug: adapterName="5a", debug_string="OPEN timeout (0x13): dev 5b.13.13 (5:000039:7385204:66), cdb 0x2a:236f16d8:0200 (0/29311), NDU 0x0" Oct 24 18:17:51 filer1a pmcsas_intrd_1: sas.adapter.debug: adapterName="5a", debug_string="Bad device state completion: status 0x39, dev 5b.13.13, cdb 0x2a:236f16d8:0200" Oct 24 18:17:51 filer1a pmcsas_intrd_1: sas.adapter.debug: adapterName="5a", debug_string="Bad device state completion: status 0x39, dev 5b.13.13, cdb 0x2a:236f18d8:0200" Oct 24 18:17:51 filer1a pmcsas_intrd_1: sas.adapter.debug: adapterName="5a", debug_string="Bad device state completion: status 0x39, dev 5b.13.13, cdb 0x28:236f3620:0010" Oct 24 18:17:51 filer1a pmcsas_intrd_1: sas.adapter.debug: adapterName="5a", debug_string="Bad device state completion: status 0x39, dev 5b.13.13, cdb 0x28:1555e6f8:0080" Oct 24 18:17:51 filer1a pmcsas_intrd_1: sas.adapter.debug: adapterName="5a", debug_string="Bad device state completion: status 0x39, dev 5b.13.13, cdb 0x2a:236f1ad8:0200" Oct 24 18:17:51 filer1a pmcsas_intrd_1: sas.adapter.debug: adapterName="5a", debug_string="Bad device state completion: status 0x39, dev 5b.13.13, cdb 0x2f:041a4800:0400" Oct 24 19:21:46 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="OPEN timeout (0x13): dev 1a.15.22 (5:000039:73850ad:19), cdb 0x2a:2368ed60:0200 (0/18656), NDU 0x0" Oct 24 19:21:49 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.15.22, cdb 0x2a:2368ed60:0200" Oct 24 19:21:49 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.15.22, cdb 0x2f:04dd0800:0400" Oct 24 19:24:01 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="OPEN timeout (0x13): dev 1a.15.0 (5:000039:7481142:e5), cdb 0x2a:2382c048:0200 (0/33634), NDU 0x0" Oct 24 19:24:01 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.15.0, cdb 0x2a:2382bc48:0200" Oct 24 19:24:01 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.15.0, cdb 0x2a:2382c248:0200" Oct 24 19:30:02 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="OPEN timeout (0x13): dev 1a.16.19 (5:000039:7480858:65), cdb 0x2a:23ca4d38:0200 (0/74568), NDU 0x0" Oct 24 19:30:02 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.16.19, cdb 0x2a:23ca4f38:0200" Oct 24 19:31:21 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="OPEN timeout (0x13): dev 1a.15.0 (5:000039:7481142:e5), cdb 0x2a:23f9dd80:0200 (0/439), NDU 0x0" Oct 24 19:31:21 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.15.0, cdb 0x2a:23f9df80:0200" Oct 24 19:31:34 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="OPEN timeout (0x13): dev 1a.15.2 (5:000039:7480859:bd), cdb 0x28:0871dd38:0008 (0/74660), NDU 0x0" Oct 24 19:31:34 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.15.2, cdb 0x2a:23fca318:00e8" Oct 24 19:33:40 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="OPEN timeout (0x13): dev 1a.16.6 (5:000039:7481143:01), cdb 0x2a:24176530:0198 (0/74786), NDU 0x0" Oct 24 19:33:40 filer1a pmcsas_intrd_2: sas.adapter.debug: adapterName="1a", debug_string="Bad device state completion: status 0x39, dev 1a.16.6, cdb 0x2a:241766c8:0200" [View Less]

Culprit...
by Carl Howell 21 Oct '16

21 Oct '16

I've got an aggregate on a FAS2554c, running ONTAP 9, that runs at over 4500 read IOPS constantly. All of the volumes in the aggregate don't generate near that many IOPS and SnapMirror doesn't look like the cause either. I've used OCUM, statistics show...., etc, and haven't been able to find out what's causing this. Any suggestions? Thanks, --Carl

SnapMirror policy clarification
by Ehrenwald, Ian 17 Oct '16

17 Oct '16

Hello I'm trying to understand the differences between the snapshot policies included in cDOT 8.3, namely DPDefault and MirrorAllSnapshots. The documentation really isn't clear and apparently I can't see it myself. The behavior I'm seeing with a DP relationship using the DPDefault policy looks like it mirrors all snapshots and the active filesystem, which the MirrorAllSnapshots policy sounds like it should do. If I delete a snapshot on the source side and do an SM update, the snapshot is … [View More]

IOM3 and IOM6 on same loop
by John Adams 10 Oct '16

10 Oct '16

Hello, I currently have 3 DS4243's with IOM3 connected to my 8020 HA pair. I also have DS2246 with IOM6 as the last shelf on the loop. I want to add a another DS2246 with IOM6 to the loop. I know that IOM3 and IOM6 can exist on the same loop as long as there was only one IOM3 to IOM6 transition. Will there be any issue adding the 2nd shelf with IOM6 to this loop? i.e.: current: IOM3 -> IOM3 -> IOM3 -> IOM6 new: IOM3 -> IOM3 -> IOM3 -> IOM6 -> IOM6 Thanks.

RE: Frame discards on Brocade with 7-Mode FMC using 8G HBA and DS14
by andrei.borzenkov＠ts.fujitsu.com 04 Oct '16

Hi, Yes, UTA2 do not support direct connection of DS14 because they do not support FC-AL. They are supported in FMC though for connection to backend switches and that is what we have here. It is clear that setting HBA to 8G won’t make DS14 faster. Still customer has also ATTO 6500N and any future storage extension will go over ATTO as well so it is still beneficial to use full available speed. --- With best regards Andrei Borzenkov Senior system engineer FTS WEMEAI RUC RU SC TMS FOS [cid:… [View More]image001.gif@01CBF835.B3FEDA90] FUJITSU Zemlyanoy Val Street, 9, 105 064 Moscow, Russian Federation Tel.: +7 495 730 62 20 ( reception) Mob.: +7 916 678 7208 Fax: +7 495 730 62 14 E-mail: Andrei.Borzenkov(a)ts.fujitsu.com<mailto:Andrei.Borzenkov@ts.fujitsu.com> Web: ru.fujitsu.com<http://ts.fujitsu.com/> Company details: ts.fujitsu.com/imprint<http://ts.fujitsu.com/imprint.html> This communication contains information that is confidential, proprietary in nature and/or privileged.

Statistic is collected several minutes after resetting counters. netapp2_fcsw1:admin> porterrshow frames enc crc crc too too bad enc disc link loss loss frjt fbsy c3timeout tx rx in err g_eof shrt long eof out c3 fail sync sig tx rx ======================================================================================================================= 0: 124.5k 90.9k 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1: 327.5k 290.8k 0 0 0 0 0 0 0 3 0 0 0 0 0 0 3 2: 278.4k 244.0k 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3: 27.0k 29.1k 0 0 0 0 0 0 0 102 0 0 0 0 0 0 102 4: 426.5k 474.3k 0 0 0 0 0 0 0 324 0 0 0 0 0 324 0 5: 41.9k 48.9k 0 0 0 0 0 0 0 120 0 0 0 0 0 0 120 6: 98.8k 109.8k 0 0 0 0 0 0 0 6 0 0 0 0 0 0 6 7: 111.4k 133.1k 0 0 0 0 0 0 0 2 0 0 0 0 0 0 2 8: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 9: 56.2k 64.0k 0 0 0 0 0 0 0 1 0 0 0 0 0 0 1 10: 13.4k 14.9k 0 0 0 0 0 0 0 52 0 0 0 0 0 0 52 11: 46.4k 50.4k 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 12: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 13: 22.0k 23.8k 0 0 0 0 0 0 0 38 0 0 0 0 0 0 38 14: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 15: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 16: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 17: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 18: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 19: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 20: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 21: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 22: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 23: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 I could not find any best practice or recommendation regarding port speeds in such configuration (actually, documentation recommends setting port speed to maximum supported by connected device, which in this case means 8G). After forcing HBA back to 4G the above messages and c3 discards went away. So I'm looking for practical experience in this area. May be there are some settings we missed. Switches are running 7.0.2b (minimal version matching IMT). Shelf firmware is the latest.
