RE: Spare disks and SnapRestore

Actually, spares don't count as far as the software limits are concerned. Data Ontap will prevent you adding disks to a live volume if you are hitting the volume or total filer storage limits, but the number of hot spares is only limited by the available id's on the FCAL loop. Tested on Data OnTap 6.2.2 and Data Ontap 6.3 regards, Alan McLachlan Senior Systems Engineer Storage Management Solutions ASI Solutions www.asi.com.au Ph +61 2 6230 1566 Fax +61 2 6230 5343 Mobile +61 428 655644 e-mail amclachlan(a)asi.com.au . -----Original Message----- From: Jacek Nogala [mailto:jacek.nogala@solidex.com.pl] Sent: Thursday, 23 January 2003 9:16 PM To: toasters(a)mathworks.com Cc: Charles Bartels Subject: ODP: Spare disks and SnapRestore > The first is regarding spare disks.

SnapRestore enables you instant reversion to the selected snapshot state of the whole volume (all Data ONTAPs) or single file (Data ONTAP 6.2 or later). "Instant" means without copying data. Actually only necessary pointers are copied. You have to be aware of the following drawbacks: - It is one-way trip (you are loosing all SnapShot copies that were collected after the SnapShot that you selected for reversion). - SnapRestoring of single file has negative performance impact (this operation causes fragmentation of WAFL file system). I hope this helps. Best regards, Jacek Nogala --------------------------------------------------------------------------- Jacek Nogala __________ Inzynier Konsultant /______/__/ Al.

Spare disks and SnapRestore
by Charles Bartels 23 Jan '03

23 Jan '03

Hi, I have a couple of questions. The first is regarding spare disks. I'm going to have a fully loaded F810 soon; 2 shelves with a total of twenty-one 72GB drives. Since I will have spare slots in the shelves I was wondering if I can setup the netapp with a 22nd drive as a hot-spare instead of "wasting" one out of my 21 disk pool. The specs on the F810 say it maxes out at 1.5 TB raw which I will be hitting with the 21 drives. And a much more general question; what does SnapRestore do? I believe this is a separately licensed option and I haven't really been able to glean too much from the Netapp website. Thanks. -Charles Bartels

Clearcase_abld user
by Clawson, Simon 22 Jan '03

22 Jan '03

Hello, A question for anyone running clearcase in a mixed environment... We have a PC domain and a UNIX domain. Each has users accessing clearcase. I have currently created the clearcase_abld user in the UNIX domain, and made him a member of a group. I have also created a clearcase_albd user in windows, and made a group with he same name as the UNIX group. However, I am told this is quite an unusual way of doing this, and a more normal approach is to create a user map in the Netapps usermap.cfg file which maps clearcase_albd to a user in the UNIX domain who will have right to the vobs etc. Any one have any suggestions on the best approach? Thanks Simon Simon Clawson Mentor Graphics HDL Designer Series R&D Rivergate Systems Administrator London Road Berkshire RG14 2QB TEL: 01635 811409

RE: FC8 disks in an FC9 shelf
by Timothy Naple 22 Jan '03

Art, There were (4) different 18GB disks used in the StorageShelf FC8's and FC9's: X221A FC8 Only X221B FC8 Only X221C FC8 & FC9 X221D FC8 & FC9 A couple years ago we tested the X221A's and X221B's in FC9's for a few weeks to satisfy our own curiosity. We found no problems. We would never recommend this to a customer and it is always best to follow the guidelines listed. You should review the NetApp Disk Drive & Firmware Matrix on the NOW site. I hope this answers your questions.

migration to new switch: questions
by pdunkin＠lucent.com 20 Jan '03

20 Jan '03

All the equipment in the server room has to be moved from a Cajun P550 switch to an Alpine 3808 Extreme switch, including our filers: an F760 with 9 Ethernet ports, an F740 with 4 ports, and an F230 with one port. - Is it necessary to bring down the filers before changing out the cables, or is it possible to get away with leaving them up and just unplugging the old cables and plugging in the new ones? - With the F760, eight of the ports are on two boards, and the ninth is a separate port labeled 10/100 BASE-T. If the system can remain up during the migration, does it matter what order the ports are moved? Also, if anyone has experience with this sort of migration, I'd appreciate any warnings, suggestions, or sadder-but-wiser advice (i.e., things you wish you'd known before you migrated your equipment) you can offer. We've already been warned to turn autonegotiation off and nail up the speed and duplex state on the Extreme. Thanks! -- Patricia Dunkin Lucent Technologies pdunkin(a)lucent.com 600 Mountain Avenue 2F-213 Phone: 908-582-5843 Murray Hill, NJ 07974-0636 Fax: 908-582-3662
