Snap restore hung...
by Mats.Oberg＠tietoenator.com 31 May '05

Hi, I was going to test snap restore the other day on one of our filers, it didn't work out the way I was hoping... Anyway, the problem was that the volume is snapmirrored to another filer and the "snap restore" told me that you can't restore on volumes that are snapmirrored. I didn't think that was a big problem until today I discovered that the snapmirroring stoped at around the time I tried the restore.. So now I have a volume that can't do snapshots anymore.. I couldn't even take the volume offline because the snap restore is still running (But restoring a single file shouldn't really take a week to complete, right?) Anybody know how to kill the snap restore?(or remove the lock/flag) I'd rather not reboot unless theres no other option. (the filer is a fas920 running 7.0.0.1p6 if thats any help...) / Mats

ISCSI boot problems.
by Jeff Mohler 28 May '05

28 May '05

Ive got the Qlogic 4010c card, and so far NO problems at all, except I cannot transfer an existing HDD partition to it, and boot from it. Ive created the LUN, windows mode, and using Ghost I can see it, and do a disk to disk transfer of the old C: drive to the LUN. Then it wont boot, I get the PC error that it cant find anything to boot from. The Qlogic card during boot sees the Lun, and there is even a few moments of activity to the LUN before the PC says it cant. Ive even re-ghosted with the 'copy boot sectors' option no to avail. I can start an XP install from the CD, using the driver floppy, and it will install files, and boot just fine, fast too I might say. If I let XP restart for the disk based install from the LUN, it runs fine, so I reboot again into ghost off a floppy, and go to Xfer the HDD image to the LUN. Same error as the first try..cant boot. Any idears?? I need to work up a plan to migrate from HDD to LUN, and it cant be a dynamic LUN either..so I cant do a simple mirror operation.

Qlogic 4010c Feedback

Other than I had up update the BIOS and Firmware to the latest levels (and that the BIOS in the card when I got it reported corrupted), I found the instasllation and configuration of booting via iscsi on the netapp to be pretty painless. Thumbs up from my end.

hrm, i am also seeing odd cpu issues with 7.0.0.1 on some new deployments. with only a few systems we are constantly over 75% cpu and alot of times well into the 90's steadily on cpu usage. i havnt seen anything related on NOW yet. -----Original Message----- From: owner-toasters(a)mathworks.com on behalf of Langborg Tom Sent: Thu 5/26/2005 6:10 AM To: 'Jay(a)Williamsons.org'; toasters(a)mathworks.com; am-utils(a)am-utils.org Subject: SV: amd / netapp issue?

RE: NDMP and IBM Tivoli
by Bui, Marcus 24 May '05

Mark, You can accomplish the same by 'zoning' the tape to the Filer. Connect the Filer to a SAN switch with the tape library. On the SAN switch, you zone the number of tape drives you want dedicated to the Filer. The Filer will essentially see the tape as local attached. I'm not familiar with the 349x but I would think you can 'zone' out some tape drives in the library.
