Re: SnapManager SQL Errors
by Raj Patel 27 Jun '08

Oliver pointed me in the right direction - After the email to check the preferred SAN address I noticed the SAN was connected via the Data VLAN and not the iSCSI VLAN. The DBA's had also renamed the server which meant the initiator was keeping the drive mapped but it was possibly affecting mounting the snaps – I disconnected and reconnected with an updated initiator name to match the new server name & reconnected on the correct VLAN and it sorted things out. Cheers, Raj.

Hi, Its a Windows 2003 sp 2 VM server (running on ESX 3.5) using SnapDrive 4.2.1 and SMSQL 2.1.1 and SQL 2005 Three luns f:/g:/h: for database, logs & tmpdb Verification server is the same as the SQL server (ie it does its own dbcc check) The SAN connection is via IP address - what needs to be able to resolve to what ?

Re: Deleting files from snapshots
by Fox, Adam 26 Jun '08

26 Jun '08

There is no approved or unapproved way to do this. It's not possible. The closest thing you can do is to put a Datafort in front of the controller and encrypt everything. Then you can shred the keys that encrypted the files in question. It doesn't delete them per se but it makes them unreadable. -- Adam Fox ------------------------ Typed with my thumbs on a very small keyboard. ----- Original Message ----- From: Francois Joubert <francois.joubert(a)imagination.com> To: NetApp Toasters List <toasters(a)mathworks.com> Sent: Thu Jun 26 11:00:46 2008 Subject: Deleting files from snapshots Hi Is it possible to delete a limited set of files from all snapshots without having to delete every snapshot in which those files appear?

SNMP netapp mib question
by Corey Hart 25 Jun '08

25 Jun '08

Hey Guys, So I have used toasterview in the past without any issues, but today I installed it at my new job and I have a question. When running an snmpwalk against the filer, and running the command uptime I see the filer uptime as DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (1664185295) 192 days, 14:44:12.95 But when toastview runs it pulls cpuUpTime for the system uptime shows as 9:23:36:01.60 So my question is what is the difference between cpuUpTime and sysUpTimeInstance ?

I have enough free space, but when I built my aggregate I didn't have the raid size set properly, so now I have one plex with only 4 disks. Not a good thing when using DP.

Quota panic in 7.2.5
by JONES P.S. 20 Jun '08

20 Jun '08

We've just moved to Ontap 7.2.5 to solve a panic problem with our previous 7.2.2 release. However we've immediately been hit with another panic which appears related to quota initialisation. The bug number/title says :- 300385 / Quota doesn't seems to be prealloc while handling multiuser members But we have less than 1000 entries in our user quota file for this volume, although it is mixed mode and draws from a user population of around 25,000 across AD and NIS. Currently we are running without quotas; not good for an extended period because we have downstream repercussions related to snapvault replicas which are designed to be 'near limit'. Just a warning for anyone with similar user numbers to be aware of. ...

Flaw with SATA disks - not suitable for deduplication environment
by Chong, Jenson 13 Jun '08

13 Jun '08

Hi, Anybody have insights on this article? Does our ONTAP "Lost Write Protection" address this issue? Regards, Jenson A bit of a flaw with SATA disk drives June 03, 2008 By Jerome Wendt Network World Asia High-capacity serial ATA (SATA) disk drives are now a mainstay in many storage systems and make it feasible for almost any company to obtain a storage system with terabytes of capacity at a reasonable cost. Yet these systems reveal a specific, known deficiency of SATA disk drives that demand companies exercise caution as to what environments they deploy these systems into. A minor flaw with SATA disk drives that high capacity storage systems expose is their bit error rate. Bit errors occur infrequently - about once for every 100 trillion bits. However RAID technology, which is normally used by storage systems to protect against data loss, does not detect if a specific bit on a SATA drive becomes unreadable. While this is normally not a problem on smaller systems, as storage systems add more capacity, the issue becomes more acute. On systems with more than 10TB of capacity the probability of a specific bit of data becoming unreadable is a distinct possibility. On systems with over 100TB, it becomes almost a certainty. So the question becomes: Does losing access to one bit of data really matter? Often, it doesn't unless one stores deduplicated data on these systems which is now the fastest growing trend in data storage. When data is deduplicated, the storage system's need to read every bit of data becomes paramount. The inability to access even a bit of data can result in multiple files becoming unreadable since they all may depend on a specific bit of data to complete their reconstruction. High capacity SATA-based storage systems are the answer to many companies' archiving and backup problems. But SATA bits can bite and using SATA drives to store large amounts of deduplicated data is not always the match made in heaven that vendors make them out to be.
