Thanks! I got some progress with that. I was able to priv set advanced and 'disk unfail' while the system was up. I should have searched NOW.

How to re-fail a disk to trigger autosupport?
by Adam McDougall 23 Sep '08

23 Sep '08

We had a disk fail in a shelf on a filer with expired support, which created a case at the time but it was closed without replacement due to lack of support on the filer. However, as part of the support agreement on a new cluster, it was in a shelf that would be covered when attached to one of the new filers. Now that we have that shelf attached to the new filer, all I get is: Mon Sep 22 17:18:22 EDT [hostname: disk.init.failureBytes:error]: Disk 0b.23 failed due to failure byte setting. I tried replugging the disk and all I got was the same message in the log. After the message in the log, the filer acts like the disk isn't present as per commands below. How can I trick it intro triggering an autosupport so my bad disk gets replaced? Thanks. > disk fail 0b.23 disk fail: Disk 0b.23 not found > disk show 0b.23 DISK OWNER POOL SERIAL NUMBER ------------ ------------- ----- -------------

Thanks for all the answers. Most of these methods of obtaining information I as already familiar with, but it's good to know that I shouldn't be looking for a one-size-fits-all command at this moment. Best regards, Filip

Just out of curiosity, why do you want to revert to 7.2?

I've had the same problem.

Test tape read speed
by A Darren Dunham 19 Sep '08

19 Sep '08

I'm trying to restore a file on a filer (via NetBackup) and the restore is *crawling* (a few KB/s on avg). One test I'd normally do would be to simply mount this tape up on the system and test that I could read it quickly. Is there any way to do this directly on the filer? I see 'dd', but I don't see how to read from the tape device. I don't think I can run a 'restore' because the data on the tape will be wrapped with NetBackup header information. I just want to test that the data can be read quickly. So actually interpreting the data isn't important at this point. Thanks. Background: Directly attached LTO3 drive. Backups are normally nice and speedy (50+ MB/s). ndmpd probe suggests that it's read 15GB of data in over 24 hours. *way* too slow. -- Darren

Identify traffic per IP address without using pktt
by Filip Sneppe 18 Sep '08

18 Sep '08

Hi, When using "sysstat" from the command line, it's very easy to get an idea of the network throughput that is currently being handled by the filer, and with commands like "vif stat" it's easy to get an idea on the interfaces that are transmitting or receiving this traffic. However, I am wondering if is it possible to get an idea on the client IP addresses that are generating most of the network traffic without having to resort to pktt every time, then copying over the capture file and analyzing it afterwards ? Are there any counters availble from a command that show how much traffic a particular IP address has sent/received ? I tried various commands (eg. netstat has a few interesting options) but couldn't find anything that solved my problem. At the moment, if I need to determine the hosts that are using most of the iSCSI or NFS bandwidth, I have to resort to pktt, and I am looking for a easier way to achieve what I want. Ideally, I'd like to get information on the protocols and ports involved too, but having IP addresses would already be very useful. Best regards, Filip

Hi Smart switches can do that for you usually (if they're smart enought) so I would rather look here.
