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

AFF and 4:1 guaranteed efficiency
by jordan slingerland 28 Sep '16

28 Sep '16

Sales guys are promising me 4:1 dedup ratios on an AFF with ontap9. They say they grantee it. I have specifically asked what stipulation. In a VDI environment with linked clones, etc. Sales guy tells me none and even specifically says they can dedup compressed video or audio (mp3) 4:1. I have A LOT of trouble believing that. So, 4:1 dedup guaranteed or what? Any comments welcome. --Jordan

Hi all, been seeing quite a bit of this error recently, and I wondered if anyone had seen this before? It looks like e either the user, or software, is trying to connect to the admin share, but could also just be trying to walk the share tree ,maybe? Full error reads:- Nblade.cifsSameTreePerSess: Received too many connection requests to the same share from one session: clientIP:port share "ipc$", user " removed IP and userid.

lun expansion
by Rhodes, Richard L. 08 Sep '16

08 Sep '16

Hello! Data ONTAP Release 8.1.2P1 7-Mode Luns fibrechannel attached to IBM pSeries with AIX Vols containing luns are snapmirrored to a DR site, and also snapvaulted to another filer. I'd like to try out resizing a lun (FibreChannel attached to AIX) to increase it's size. Have never done this! I know OnTap can resize a lun. What I'm not sure about is how that works with snapmirror and snapvault relationships. Snapmirror is at the volume level and shouldn't care. But snapvault in 7-mode is still at the object level - it works on the lun file. But then, SV should just copy the new blocks. So, I'm thinking lun expansion is no problem with SM and SV. Is this correct? Thanks!

cDOT 8.2.x, grow aggregates or new ones?
by John Stoffel 08 Sep '16

08 Sep '16

Guys, I've got a four node, 8060 cluster running cDOT 8.2.x which we just added in a bunch of disks, spread evenly across our two HA pairs. 2 x DS4246 x 2Tb SATA, and 4 x DS2246 x 600g SAS shelves/disks. I suspect the smart thing to do is to just grow my existing aggregates, which lets me grow existing volumes, etc without too much trouble. And of course I would add in disks in complete Raid Groups. Or do people think I should just create brand new aggregates and move as needed? Do I really need to worry about reallocation issues when I do these adds? My current setup is: n1sas1 20.67TB 7.37TB 64% online 28 n1 raid_dp, n1sata1 56.75TB 12.15TB 79% online 79 n1 raid_dp, n1sata2 56.75TB 7.30TB 87% online 99 n1 raid_dp, n2sas1 26.92TB 6.19TB 77% online 20 n2 raid_dp, n2sas2 26.92TB 9.51TB 65% online 29 n2 raid_dp, n2sas3 20.19TB 9.54TB 53% online 6 n2 raid_dp, n2ssd1 13.09TB 10.84TB 17% online 7 n2 raid_dp, n3sas1 26.92TB 7.24TB 73% online 31 n3 raid_dp, n3sas2 26.92TB 8.13TB 70% online 37 n3 raid_dp, n3sas3 20.19TB 2.97TB 85% online 50 n3 raid_dp, n4sata1 56.75TB 9.73TB 83% online 69 n4 raid_dp, n4sata2 53.84TB 9.46TB 82% online 33 n4 raid_dp, As you can see, we did screw up in n1/n2 by having both SAS and SATA aggregates on the same head. Ooops. We fixed that for the second pair when we grew the cluster. Just looking for a confirmation of my thinking. Thanks, John

Ontap SELECT SSD
by BERNTSEN Basil 07 Sep '16

07 Sep '16

Hi folks, I was told by someone on my account team that SSD isn't "allowed" on Ontap SELECT. That said, I found in TR 4517, page 9, (http://www.netapp.com/us/media/tr-4517.pdf) that in fact we can use SSDs. Anyone here know the whole story? · If I attach a bunch of SSDs to a RAID card and present them to an Ontap SELECT VM, can I use them? · Will it try to use them like spindles, without any of the new 9.0 flash optimizations?
