Re: Truncated SSH ouptut on 8.x?

I just got a nice reproduction, and the data I got really surprised me. (BTW, the filer I'm hitting below is running 8.0.1P2). I have a script that checks "qtree stats" periodically. And to save on SSH setup/teardown costs, it runs a sysstat in the same command. But the script then works through the data and hands back a summary. I don't have a copy of the raw stuff coming back. But I saw some oddities that made it appear that it was not getting all the data. So I ran the following command and was going to put it in a crontab to run mutliple times so I could see if it went off. "qtree stats; sysstat -c 1 5" Well, while testing the script, on the 4th time I ran it I got "short" output. On this filer, that command should return 179 lines. On the last try it only returned 10, but not simply the first 10. Here's a (slightly obfuscated) version of what I got back: -----BEGIN No qtrees are in use in Volume vol0 Volume Tree NFS ops CIFS ops -------- -------- ------- -------- perf [user]perf 1773 0 Volume Tree NFS ops CIFS ops -------- -------- ------- -------- test_vm_volume vm_vol 0 0 CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 77% 28350 0 0 290677 82179 194167 415548 0 0 6s -----END In reality, the "perf" volume has over 100 qtrees. The one shown above is the first line in the list when the command is complete. So it's not simply truncating the total output, it has managed to drop a portion of the output of one command. If it were a network or SSH problem, I wouldn't expect a gap in the middle of a command, nor would I expect it exactly on a nice line boundary. Looks like I can open a ticket now. -- Darren

Purging events in operations manager
by A Darren Dunham 26 Jul '11

26 Jul '11

If I look in my Operations manager settings (DFM 4.0.2), I see an eventsPurgeInterval. What events should be getting removed by this setting? I have lots and lots of old events cluttering things up. Some are only in history, some are current. Here's one that's current. $ dfm report view events | grep 985209 Information 985209 Aggregate Discovered 08 Dec 2008 24482 toaster4:aggr2 here's one that's not current: $ dfm report view events | grep 620491 $ dfm report view events-history | grep 620491 Information 620491 Host User Modified 15 Aug 2008 root 25 Nov 2008 1810 toaster3 But other times I see things do get purged, so I just don't understand what is and is not disappearing. Is there a way to get rid of all these ancient information events disappear (even from history)? -- Darren

VMAX and NETAPP on the same SAN
by Milazzo Giacomo 22 Jul '11

22 Jul '11

Hi all, we're going to migrate some LUN from EMC VMax array to a new 6280 on a FCP SAN. At the same time customer has to maintain on the same hosts Windows 2K3 and 2K8 LUNs on the VMAX and LUNs on the 6280. First we will push the customer to acquire another set of HBAs to physically separate the traffic and over all for we have to use two different MPIO software on the different HBAs. But the big issue is that there's no doc that certify supportability of these two environment at the same time in Windows. I found old docs reporting supportability of CX3 and CX4 but neither a word on VMAX nevertheless it's on the market since 2009. Any suggestion? Regards,

Has anyone connected to an AS400 using VIOS?
by Page, Jeremy 15 Jul '11

15 Jul '11

Since it works for AIX power boxes so I don't see why it shouldn't work for an iSeries box as well but I don't have any experience with it. From what I understand the main thing that was preventing AS400's from using a NetApp box as storage was the difference in the block sizes but that's abstracted by the virtual IO server and works with other FC boxes now.

aggregate rename
by Kennedy, Jeffrey 15 Jul '11

15 Jul '11

My question is specifically around 8CM but I would be surprised if it applied differently to 7mode. Can an aggregate be renamed without impacting NFS access by clients? Volumes cannot, obviously, but nowhere is a client aware of aggregate info so had I to guess I'd say it could be renamed with impunity. But I'd rather not guess... Thanks.

Hello Toasters, What's the easiest way to fix these ssh related errors reported by the filers? [sshd_0:info]: Postponed publickey for <user> from <client> port 47309ssh2 and also these related ones: [ems.engine.inputSuppress:warning]: Event 'openssh.invalid.channel.req' suppressed xxx times since [openssh.invalid.channel.req:warning]: SSH client (SSH-2.0-OpenSSH_4.3) from <client> sent unsupported channel request (10, env). NOW wasn't much help here. thanks in advance -net

Re: Finding out which client has mapped a share?
by John Stoffel 01 Jul '11

01 Jul '11

Kyle> How about cifs sessions *? supportnetapp01> cifs sessions * Doesn't seem to work. When I do this command, I don't see any clients mapping this share, but it still won't let me delete it. Very frustrating. John
