8.1 64 bit upgrades.
by Jeff Cleverley 22 Oct '11

22 Oct '11

Greetings, I've starting playing around with the 8.1 RC1 release. I want to upgrade some aggregates from 32 bit to 64 bit. From what I can tell, the only way to do this is to add additional disks to an existing aggregate. Is that correct? I've got one filer with limited disks and don't want to add 1 additional disk to a raid group. I don't want to do all the associated reallocates to smooth out the data allocation. Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

TOE fun?
by Mark Flint 21 Oct '11

21 Oct '11

Hi all, I recently upgraded a V3140 to 8.0.2P1, and all went well apparently. I'n now seeing strange NFS/CIFS behaviour, where a client will make a connection succesfully, but when the client requests a read, the filer FIN ACK's instantly, for no reason I can work out. Got a call open with netapp, but they seem a little fazed by it as well. Anyone seen something similar and can point me? It does seem like it's a TOE problem, but I have TOE turned off on the NIC's, but am wondering if ONTAP is doing something behind the scenes maybe?

by Luca Domenella 13 Oct '11

Hi guys, i have 2 fas2050a used only with NFS protocol. I need to reinstall one from scratch and snapmirror the data in it. After that I want to swap (one by one) the heads from the other fas2050a in order to dont change the support contract from this storage. Do you see any issue in performing the head swap ?

weird name mapping issues - using LDAP for name services
by Page, Jeremy 13 Oct '11

13 Oct '11

We are using Active Directroy for LDAP on our Linux clients. I'd like to set up the filer to be able to resolve the usernames both directions but I'm having a couple of issues. Filers are running 7.3.3. I have had this working before at a previous job but I am missing something & the docs are not quite as helpful as I'd like. 1) I can't get LDAP working at all (getXXbyYY is not working even though I see the filer connecting to the DC on the appropriate port but I'm missing something. 2) Not all users have rfc2307 information set, ideally I'd use their samaccountname for both (it always matches). 3) I am in a multiforest environment, I'd like to use Global Catalogs for my lookups instead of normal DC's & do it on the GC port so it can retrieve info for any user on my network. This may not be possible, I am not sure. NIS works fine, if I am not able to get this to work I'm either going to have to script a dump of AD to NIS or use the MS tools to do the same thing and do this with a usermap.cfg. Either possibility is ugly so any suggestions would be appreciated. I've tried changing the ldap.minimum_bind_level to simple but it does not appear to help. dr-array02*> options ldap ldap.ADdomain ldap.base dc=site,dc=company,dc=com ldap.base.group dc=site,dc=company,dc=com ldap.base.netgroup ldap.base.passwd dc=site,dc=company,dc=com ldap.enable on ldap.minimum_bind_level anonymous ldap.name cn=ldap-auth-proxy,ou=ldap,ou=services,dc=site,dc=company,dc=com ldap.nssmap.attribute.gecos gecos ldap.nssmap.attribute.gidNumber gidNumber ldap.nssmap.attribute.groupname cn ldap.nssmap.attribute.homeDirectory unixHomeDirectory ldap.nssmap.attribute.loginShell loginShell ldap.nssmap.attribute.memberNisNetgroup memberNisNetgroup ldap.nssmap.attribute.memberUid memberUid ldap.nssmap.attribute.netgroupname cn ldap.nssmap.attribute.nisNetgroupTriple nisNetgroupTriple ldap.nssmap.attribute.uid uid ldap.nssmap.attribute.uidNumber uidNumber ldap.nssmap.attribute.userPassword userPassword ldap.nssmap.objectClass.nisNetgroup nisNetgroup ldap.nssmap.objectClass.posixAccount posixAccount ldap.nssmap.objectClass.posixGroup posixGroup ldap.passwd ****** ldap.port 389 ldap.servers vm-sitedc01.site.company.com ldap.servers.preferred ldap.skip_cn_unescape.enable on ldap.ssl.enable off ldap.timeout 20 ldap.usermap.attribute.unixaccount uid ldap.usermap.attribute.windowsaccount sAMAccountName ldap.usermap.base ldap.usermap.enable on Please be advised that this email may contain confidential information.

Migrate Solaris FC LUN to Linux iSCSI ?
by Steve Losen 11 Oct '11

11 Oct '11

Hi toasters, Is it possible to take a Solaris FC LUN and attach it to Linux via iSCSI? I suspect problems since the "lun create" command needs to know the OS type (solaris in this case). I don't think FC to iSCSI is a problem, though. Naturally we would love to "just move" the LUNs without creating new Linux LUNs and copying the data from Solaris to Linux. In case you are wondering about the FS on the LUNs, this is disk cache for a StorNext filesystem and we want to replace our very old Solaris hardware with Linux "in place". Otherwise it would take literally months to migrate the data since StorNext is a tape backed hierarchical FS. If we can't do this hardware upgrade in place, then we will soldier on on the old Solaris hardware and cross our fingers. We intend to replace StorNext eventually but want to get off the old Solaris hardware in the interim if possible.

Snapvault advice
by Unnikrishnan KP 07 Oct '11

07 Oct '11

Hello all, We are planing a snapvault backup of data from a snapmirror destination. Most of the volumes that are to be snapvaulted are luns in qtrees. The rest are nas data. I was looking at different ways to do this and came up with the following conclusion for block data: 1. Run a snapvault update on the _recent copy. Schedule a snapvault snap sched on the secondary after the update. This require a bit of scripting and schedules. 2. The best practises guide recommends using the SnapManager product for sv backups. Since this too require a level of scripting; I am not sure what difference it would make. Also this requires rsh access to the filers which we do not permit. As for the NAS volumes; the snapmirror source will need to be setup with a snavault snap sched schedule (something that happens before a snapmirror transfer). This snapshot will then be snapmirrored to the SM destination. The SV secondary snapvault schedule will have a snapvault -x schedule that happens after the SM transfers complete. The other option would be to follow the same pattern as option 1 used for block data. Just wondering if any of you have faced this issue and what was done in your environment? Any feedback on this will be apprecated. Regards, Unnikrishnan KP

Cleaning up snapshots while leaving flexclones
by Fletcher Cocquyt 04 Oct '11

04 Oct '11

Hi, We routinely cleanup snapshots via filerview and recently started using flexclones, which show up in the snapshot view as ³busy,vclone Busy² For this volume there are similarly named snapshots listed as ³normal² We¹d like to delete those to reclaim the space, but want confirmation they are not going to affect the mounted vclone(flexclone) volumes. Basically I am asking will filerview prevent me from deleting these snapshots if they are associated with an actively mounted flexclone? ( Thanks -- Fletcher Cocquyt http://vmadmin.info

Use license on different filer.
by Liniger Pascal 03 Oct '11

03 Oct '11

Hello, Is it possible/allowed to use a license on a filer other that the one to which the license is associated in NOW? Let's say I have a FAS2020 with a snapmirror license and I have no use for the license on this particular system, can I use this license on another FAS2020?

Linux Mutipath to NetApp LUN via FCP
by Paul Letta 03 Oct '11

03 Oct '11

Hi Everyone. This question is probably more Linux than Netapp, but I figured people on this list have done this. I am setting up DM-Multipath with a lun from a FAS via FCP. I have the NetApp linux host utilities installed on the host. I have a LUN that has 2 paths (one lun, 2 HA FAS controllers). Without Multipath running, I see them as /dev/sdb and /dev/sdc: # fdisk -l Disk /dev/sdb: 322.1 GB, 322163441664 bytes 255 heads, 63 sectors/track, 39167 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 39167 314608896 83 Linux Disk /dev/sdc: 322.1 GB, 322163441664 bytes 255 heads, 63 sectors/track, 39167 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdc1 1 39167 314608896 83 Linux This is correct. I can mount each of these one at a time from the host and see the LUN correctly. After I start up Multipath, I have the same 2 devices above (sdb and sdc) but TWO new devices: Disk /dev/dm-0: 322.1 GB, 322163441664 bytes 255 heads, 63 sectors/track, 39167 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/dm-0p1 1 39167 314608896 83 Linux Disk /dev/dm-1: 322.1 GB, 322159509504 bytes 255 heads, 63 sectors/track, 39166 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-1 doesn't contain a valid partition table My question is why do I have both /dev/dm-0 AND /dev/dm-1 ? Also -- above shows dm-1 as not having a valid partition table, However, when I try to mount /dev/dm-0 it fails (says its busy), but I can mount /dev/dm-1 and see the LUN just fine. So I'm looking for some basic guidance with multipath. From what I've read, I should just see one /dev/dm-* and I should be able to mount it, and it should have a valid partition table on it. Thanks ! Paul Here is the /etc/multipath.conf file: [root@zstore2 /]# cat /etc/multipath.conf defaults { user_friendly_names no queue_without_daemon no flush_on_last_del yes max_fds max pg_prio_calc avg } blacklist { devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^hd[a-z]" devnode "^cciss.*" wwid 3600508e00000000081661358cff52b01 } devices { device { vendor "NETAPP" product "LUN" path_grouping_policy group_by_prio features "1 queue_if_no_path" prio_callout "/sbin/mpath_prio_ontap /dev/%n" path_checker directio failback immediate hardware_handler "0" rr_weight uniform rr_min_io 128 getuid_callout "/sbin/scsi_id -g -u -s /block/%n" } }

Oracle and VMware Datastores
by Tommy.Fallsen＠kongsberg.com 01 Oct '11

01 Oct '11

Hi Im setting a new Oracle Database solution to replace a old Oracle RAC on EVA8400. After reading Oracle Databases on VMware vSphere 4 - Essential Deployment Tips i got a few question still needs answered. Our new storage is a FAS 3240 7-Mode We have a SATA and SAS aggregate and 1TB Flash cache available. SAS 1 Raid Group (16 disks) SATA 4 Raid Group (56 disks) Whats the recommendations for Datastores and VMDK's? >From i can gather i need to create a volume dedicated to Oracle and present(NFS) it as Datastore for Oracle only. And create VMDK's like this: VMDK-1 OS from another Datastore Oracle Datastore VMDK-2 Oracle Binaries VMDK-3 Oracle data VMDK-4 Oracle Redo VMDK-5 Oracle Archivelogs I have 5 databases so 5 VM's where i create a volume with Datastore for each? Would like input from the list how others have done it. - Tommy Fallsen SA/DBA Grunt ________________________________ CONFIDENTIALITY This e-mail and any attachment contain KONGSBERG information which may be proprietary, confidential or subject to export regulations, and is only meant for the intended recipient(s).
