'rmtab' isn't meant to be in a very readable format, it's for the system to know what mounts are current. You may get a better view of it by using 'cat from a Unix host. You could just run 'showmount' from a unix host: [root@localhost ~]# showmount -a sim1 All mount points on sim1: 192.168.222.138:/vol/vol0 simhost:/vol/vol0 I had been uder the impression that nfs.mountd.trace would log to syslog, but it doesn't: nfs.mountd.trace When enabled, all mount requests are logged. This option is intended to help debug denied mount requests. Valid values for this option are on (enabled) or off (disabled). The default value for this option is off to avoid too many messages. The output is stored in /mountd_trace.log and can be translated by the mountd_trace.pl program. This program can be found on the NOW site. Turning the option on clears the log file and starts the logging process. Since the logs are kept in memory, the option needs to be turned off to flush the logs to the file. Hrrrm, that could chew through some memory fast with a lot mounting going on ... Hope this has been helpful. At your service, Eugene Kashpureff

Markus - It's the reconnect to the LUNs and Snapdrive part that would make me nervous. I didn't see re-establish SnapDrive mgt of luns in there. (Once you manage with SnapDrive, always manage with SnapDrive!) Leave your existing vlan up on the vif, and create a new vlan on that vif if you can get to that network/vlan ? Try a dry run with an empty LUN first ? Good luck with this migration ! At your service, Eugene Kashpureff

Root cause - more load on your CIFS shares as traffic has grown. There's a lot of information to be looked at: CPU load on the scanning servers. Network bandwidth on connection to scanning servers. Current load on the filer (CPU, Disk, cache). Have you set 'vscan extensions include/exclude' to avoid scanning files that aren't likely to be a threat ? Have you considered implementing '-novscanread' on shares deamed to be clean ? At your service, Eugene Kashpureff

I recently sat our 'VMware vSphere on NetApp (VVNA)' course for my instructor certification on the course. We use ESX 4.1 with an 8.0.1 7-mode set of simulators for the labs. It all worked well. We get a lot of feedback from students when teaching our courses. I've had a number of students running ESX 4.1 telling me that they've been upgrading to 8.0 to take advantage of 64-bit aggregates. The biggest drawback would seem to be the implied performance hit with 64bit aggrs, but I haven't heard of any bad experiences with performance. I've even had a few students who had upgraded to 8.01 to take advantage of the larger ASIS volume sizes. 'After you upgrade to Data ONTAP 8.0.1 and later from an earlier release of Data ONTAP, you can increase the deduplicated volume size up to 16 TB. ' In general folks seem to be running deduped volumes on 32 bit aggrs for their VMs, and using 64 bit aggrs for data used by those VMs ( large DBs ). Not much more detail I could give you, it's just classroom discussion feedback. Do realize that 8.01 is still in RC status when thinking about upgrading, and read through the release notes. Hope this has been helpful. At your service, Eugene Kashpureff

Of the two boot camps we teach (7 v 8-7mode) I think there's more material in our our NCDA 7 course. The 8/7mode course seems to have been trimmed down, and geared towards passing the 154 test. I prefer teaching the 7 version of the course with more material in it. See also: The previous threads on exams, where I encourage folks to study the documentation, and run the a lot for practice. It sounds like you're already on the right track ! At your service, Eugene Kashpureff

Natrian - A few questions, and suggestions: Are you looking for experience you can put on your resume, or experience to hone your skills with Data ONTAP ? For honing your skills with Data ONTAP I would suggest you install a set of four simulators - An active-active pair for primary storage, and another set for secondary storage. Spend some time setting up all the applications you can to implement these as storage for other applications - NetApp applications (SnapDrive, Ops Mgr, System Mgr, OSSV) as well as any other apps you can get your hands on - Oracle, VMware, MSSQL. Also, study, study, study. You passed your NCDA, but keep reading. Go through Data ONTAP release notes, as well as all the guides. As you read, do test implementations. Browse and read through all of the TRs at www.netapp.com/us/library. For resume working experience you may want to contact very large charity organizations. I had a student in one of my NetApp classes a few months ago who did volunteer time as an admin for the Red Cross. Hope this has been helpful for you. At your service, Eugene Kashpureff

Alberto - I haven't ever heard a story of the 'mixed' security style working out well for users. Even if you were able to get permissions to copy over correctly to start with, over time the mixed security style turns into a hair ball as unix/windows users change the security styles of files they have access to. It's usualy best to decide that the given data is going to be unix or ntfs data, then correctly configure multi protocol for the access you need from the other side. When tring to decide what security style to use the question I ask is 'Which side needs to control write access to the data ?'. Robocopy works great for migrating Windows file systems, but for unix file systems consider using native unix tools... At your service, Eugene Kashpureff

Take a look at your syslog for command line authentication. (/etc/messages) You'd get mount traces in /etc/messages if you enable: nfs.mountd.trace on But it's turned off by default. Also take a look at your audit log - /etc/log/auditlog (grep for 'exportfs' commands or API calls) Ooops - who mounted ? see: /etc/rmtab (that's what I get for answerring too quickly!)

Jared - I'm a NetApp U instructor for Fastlane. Our 'Training Materials' are in the form of courseware and lab guides. Each student registered for a NetApp class gets courseware that goes with that class. You can visit the NetApp U web site at: http://www.netapp.com/us/services/university/university.html . You may wish to visit http://www.fastlaneus.com/ and take a look at the Fastlane available courses and schedules. You don't need to take NetApp U classes to get access to documentation, which I constantly refer students to. Documentation can be downloaded from the NOW site http://now.netapp.com/. Access to NOW is granted based on a supported serial number when you register for your NOW account. Multiple folks at your company can register using the same serial #.

Scott - Which of the OSSV licenses are free ? All of them ? Please, tell us, we sooo try to lead clients down the right road. This is important stuff to us instructors - we love to tell clients about free licenses ! At your service, Eugene Kashpureff

OSSV is licensed on the filer on a per seat (license pack) basis for various clients. It used to be just sv_unix_pri and sv_windows_pri, and the licenses were not additive. I just ran 'license' on a 7.34 simulator and found that the sv_pri license set has been greatly expanded: sv_exchange_pri not licensed sv_linux_pri not licensed sv_marketing_pri not licensed sv_oracle_pri not licensed sv_sharepoint_pri not licensed sv_sql_pri not licensed sv_unix_pri not licensed sv_vi_pri not licensed sv_vmware_pri not licensed sv_windows_ofm_pri not licensed sv_windows_pri not licensed It seems the licenses have been split out, including seperate licenses for using the integration with SMO, SME, SMSQL and SMVI.

Miroslav - I haven't seen any cases where the simulator can't be implemented to do test/lab/demos of NetApp technology. We've been using simulators very extensively over the past two years. We use simulators for classroom labs for many of the NetApp classes we teach. We implement Snapmirror, Snapvault, SMO, SME, SMSQL, SMVI, and Operations Mgr. in VM environments using the simulator...

Daniel - It's not likely ! In the old days there were 10g disks for the sim, but NetApp found that folks were using the sim in production situations. Hence, the current limitations of using 1g simulated drives and only 28 simulated disks. Given that you're qouting a 50g size, I'd guess you've already found the hack to change maxdisks to 56. But you won't be able to do cluster failovers. I don't find it to be a limitation for snapdrive or any other software you want to use with the sim. Just create smaller LUNs.

Michal - See the 'disk_fw_update < disk_list >' command to update disk firmware. This usualy done automagicly while doing an upgrade. Current disk firmware should already be loaded on with the software release. There were some issues doing the update with 7.2 > 7.3 on SATA drives, see the release notes. As for the cluster messages - not a clue ! : ) At your service, Eugene Kashpureff
