FAS backup question
by Mike Gossett 15 May '13

15 May '13

Greetings: I have a general question in regards to backup solutions for NetApp filers. We have a client that is in the process of purchasing a FAS-2240-2 HA, and will be purchasing a FAS2220 for a DR site later this year. We are getting the complete license bundle to have SnapManager backups for VMWare, Exchange, etc to local disk, and licensing SnapMirror on the FAS2220 for replication of current data. It is our intent to implement some slower SATA disks to maintain longer retention windows. However, this environment is very interested in additional backup measures beyond that. Historically we have been using BackupExec, using agents on physical servers and VMs, to backup to both a NAS device and LTO autoloader. I am a little confused on how we can effectively accomplish an efficient backup of these filers outside of the netapp ecosystem. I have seen evidence of other users with older or larger models using direct-attach SCSI tape autoloaders (or FC autoloaders) with NDMP. We can't implement the SCSI cards in the 2240, and we don't wish to have the budgetary hit of implementing FC solely for tape connections. We were prefer to avoid tape altogether, if at all possible, as these filers will be in collocation facilities that we don't otherwise physically visit. Some other background: most\all of the data on these 2240s will be VMWare VMs stored on NFS (thin) datastores. There may be one or two iSCSI connections from VMWare for SQL and Exchange for SME reasons. The environment is a MS shop, with Sharepoint\SQL being the critical business application. Does anyone have any recommendations about other ways to backup our data? We hope to rely on the NetApp replication and SnapManager\SnapRestore\SnapVault for most of our normal recovery needs, however require the safety net of a weekly or monthly backup to some other media. We also hope to avoid something that is too difficult to manage, and were hoping for a commercial solution. Backup Exec with appropriate agents and a local NAS device or something along those lines is what I was thinking. Does anyone have any experience with tape devices connected to a media server backing up NetApp filers? Can NDMP stream the content to the NDMP backup server with a locally attached autoloader? How about some other sort of disk target (e.g. cheap NAS appliance connected to the backup server via cifs \ iSCSI) I've reached out to my SE, who indicated that most organizations are either using FC\SAS\SCSI autoloaders with NDMP or are relying on the built-in NetApp SnapVault solution. I would welcome any guidance or experience that anyone can share. Thanks, Mike Gossett

Re: RAID not reconstructing on FAS3050c

Doug, Thank you so much for your detailed reply! I have deleted the core files, removed the bad disks (now dblade 'aggr status -f' is empty), and cleared the shelf fault. But nothing else. Did some more poking around, and yes I agree, the available spares seem like they should get used ... the list of spares says "Spare disks for block or zoned checksum traditional volumes or aggregates" and my degraded aggregate says it is "block checksum". All the disks are the same block sizes, etc. Now, I couldn't figure out how to turn off the "ignore inconsistent" flag. Here's what I tried: in the cluster shell (what you get when you log in as admin(a)ip.ad.dr.ess), I ran 'set -privilege advanced' (as that seems to be what your prompt indicated), and tried 'aggr modify ...' but 'aggr' was not available. Then I tried 'storage aggregate modify ...' but there was no -ignore-inconsistent switch available (just a few: -state, -raidtype, -maxraidsize). Last, I tried running 'aggr modify ...' under the node shell (what you get when you run 'dblade' from the cluster shell), and there was no 'modify' subcommand available -- just the following: media_scrub, read_fsid, show_space, wafliron, raidlabel, scrub, status. Also, one last funny thing: looking at 'aggr status -r' in dblade, the RAID group with the failed disk seems to be stuck at "recomputing parity 0% completed". If you have any other input you are willing to provide free, I would appreciate it loads! If you'd like to take this off list let me know, more than willing to pay your fee. Thank you!

Re: RAID not reconstructing on FAS3050c

Thanks all! So far I have been able to get into the node shell and determine that the aggregate is marked as "wafl inconsistent". The disks are all the same size and model (SATA connected via FC, NetApp X267_MGRIZ500SSX), except for one, which is model X267_HKURO500SSX -- it appears to be of the same size as the rest, however, and is currently a good data disk. Around the time of the failure, this message appears in the messages.ems log: [config_thread]: raid.rg.recons.cantStart: The reconstruction cannot start in RAID group /engdata1/plex0/rg2: No 520 bps disk of required size available in spare pool That might explain why it's not reconstructing. The full messages.ems log is here: http://pastebin.com/b9Xgj628 Also here is the output of 'aggr status -r': http://pastebin.com/MmHFNbiz I'm guessing that what I need to do is run WAFL_check? Anything else I should look at before I run off and do this?

RAID not reconstructing on FAS3050c
by Chris Daniel 09 May '13

09 May '13

Hello, We've got a couple of FAS3050c filers running 4 DS14mk2 shelves full of disks (each filer is connected to two disk shelves). They've mostly been trouble-free, but this week it seems a disk failed, and our main storage aggregate went into "degraded" mode. For some reason, despite spare disks being available, it's not reconstructing as I would think it should. The software running on these filers is Data ONTAP GX 10.0.1P2 -- from previous discussions with the community, I've learned that GX has a whole different set of commands, so many of the Google-able resources I've found aren't relevant. Adding to that difficulty, we don't have a support contract on these filers (but they are properly licensed and whathaveyou). Here is the output of 'storage aggregate show -aggregate engdata1' (that is the degraded aggregate): toast1a::> storage aggregate show -aggregate engdata1 Aggregate: engdata1 Size (MB): 0 Used Size (MB): 0 Used Percentage: - Available Size (MB): 0 State: restricted Nodes: toast1a Number Of Disks: 37 Disks: toast1a:0a.16, toast1a:0b.32, toast1a:0c.48, toast1a:0a.17, toast1a:0b.33, toast1a:0c.49, toast1a:0a.18, toast1a:0b.34, toast1a:0c.50, toast1a:0a.19, toast1a:0b.35, toast1a:0c.51, toast1a:0a.20, toast1a:0d.64, toast1a:0b.37, toast1a:0a.21, toast1a:0c.52, toast1a:0b.38, toast1a:0a.22, toast1a:0c.61, toast1a:0b.39, toast1a:0d.69, toast1a:0c.54, toast1a:0b.40, toast1a:0a.24, toast1a:0c.55, toast1a:0d.65, toast1a:0a.25, toast1a:0a.26, toast1a:0b.42, toast1a:0c.59, toast1a:0a.27, toast1a:0b.43, toast1a:0a.28, toast1a:0b.45, toast1a:0d.68, toast1a:0d.71 Number Of Volumes: 0 Plexes: /engdata1/plex0(online) RAID Groups: /engdata1/plex0/rg0, /engdata1/plex0/rg1, /engdata1/plex0/rg2 Raid Type: raid_dp Max RAID Size: 14 RAID Status: raid_dp,degraded Checksum Enabled: true Checksum Status: active Checksum Style: block Inconsistent: true Volume Types: flex There are spare disks available now, but there were not when the failure occurred. I moved two spare disks to the right filer after the failure, thinking that would cause the aggregate to start reconstructing.

Can anyone provide insight on this problem? Why is the aggregate not reconstructing when there are spares available? NetApp stuff is not my specialty, but I'm the one who gets to deal with it, and I am pretty stumped. Thank you in advance! -- Chris Daniel

DataFabric Manager Question
by Ray Van Dolson 09 May '13

09 May '13

We have IBM-branded DataFabric Manager v5.0 installed. I *believe* this was replaced by OnCommand Core. Is that correct? Want to make sure I'm upgrading the right product and there isn't a newer version of DFM I should be using instead (haven't found one). Thanks, Ray

Hi Folks, I am trying to setup a pair on thin volumes that will be used in snapmirror relationship I was going to use these netapp recommend volumes Autodelete Configuration guarantee = volume LUN reservation = enabled fractional_reserve = 0% snap_reserve = 0% autodelete = volume / oldest_first autogrow = off try_first = snap_delete So I did the following vol create vol1-s none aggr0 550g vol options vol1 fractional_reserve 0 snap reserve -V vol1 0 vol autosize vol1 off snap autodelete vol1 on vol options vol1 try_first snap_delete Does it play nice with snapmirror? Does snap autodelete can potentially mess up snapmirror? Thank you!

DFM user password reset.
by Jeff Cleverley 06 May '13

06 May '13

Greetings, We have a DFM server running 4.0.2. I have a remote user who can't log into the web interface. He is listed as a user and has global view permissions. He shows up in the dfm user list output. It appears he has forgotten what his password is. I've been looking around for an hour and can't figure out how to change his password so he can get into the web page. Where is it doing the authentication from? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

AW: Enabling create_ucode on volumes afterwards
by Alexander Griesser 03 May '13

03 May '13

Hi Matt, thanks for your fast reply - in the manpages it says, that create_ucode needs to be on for FCP/iSCSI volumes - is that a wrong information?

Mai 2013 17:40 An: Alexander Griesser Betreff: Re: Enabling create_ucode on volumes afterwards You really only want it on for CIFS accessed volumes. One potential issue is with reading SnapMirror destinations without create_ucode being on, on both the source and destination volumes. You will get weird errors if not, and not be able to browse files at all on the destination.

Linux Host Utilities 4.1
by Peta Thames 02 May '13

02 May '13

Hi, Anyone have a dusty old copy of Linux Host Utilities 4.1 lying around? I need to build a test cluster with RH 4.6, and I know the real fix is to upgrade the OS, but there's a world of dependencies on the app running on these servers so we need a test cluster to be able to prepare for that. Thanks, Peta
