the link seems disappeared. Can somebody PLEASE find the active link for me?

netappmagic · ‎2014-09-18

Just to see if anybody can shed a light on this issue?

I just wanted to add my 2 cents on iostat and SAR, how accutely to use these number on sizing NetApp filers? Let say, iostat on current DAS system, the output on DAS will be quite different from where the application is moving to, ex, NA or EMC, right?

Good. this is a type answer I am looking for. I can determine or calculate IOS/GB, based on disk configurations on either FAS3XXXX or FAS6XXX, but, how do I know what application requires how many IOS/GB, how do I find out what is the requirement on response time?

What about Capacity Planning? Does Operation Manager also covers that? is Performance Advisor part of Operation Manager? I saw a video before and describe functions about Operation Manager, could not find anymore. Can you please forward the link, if you could find it? Appreciate your help!

I used to work on a tool that allow me to monitor the filer performance, set up threshold on for instance aggregates/volume, disk utilization, peak I/o etc, and also set up alert based on the threshold. What tool can do all these, was that called Operation Manager? What is name of it now? There is another function that allow me to plan on the capacity, view and forecast the capacity development. Is this also called Operation Manager, or a different tool? what is the name of the tool, if it is not Operation Manager? If somebody can please shed some lights on these questions, I would appreciate it.

IO density , or IOPS/TB is more to do with disks, or raid level, less to do with CPU, or model of FAS. Please correct me, if I a wrong. Thanks!

In determining which level of filers you want to adapt, for instance, whether we should adapt FAS 3XXX or FAS 6XXX, what are those aspects should be taken into your considerations? any tools can we use to measure? The easiest part is the capacity, if the application/projects requires a large amount of data, and so large FAS 3XXX may not able to handle, then FAS 6XXX of cause would have to be used. Also, response time, and ports... etc. Could you please give some in-depth analysis? .... Thank you in advance for your inputs.

I have a volume which is already exported in /etc/exports file, for instance /vol/vol1 now I wanted to add an extra line /vol/vol1/qtree1 in exports file and export the qtree with the same volume, ex, /vol/vol1/qtree1. will that be causing any issues, could one overwrites the other? Thanks!

netappmagic · ‎2014-08-20

I need to keep DST volume for a month long. It turns out that "stop" command took about 12 hours to complete.

netappmagic · ‎2014-08-19

I have already tried "snapvault stop qtreename" on the destination, and prompts me the following message. However, it did not do anything, hanging there forever. Then still "idle" on the status. The secondary qtree will be deleted. Further incremental updates will be impossible. Data already stored in snapshots will not be deleted. This may take a long time to complete. Are you sure you want to do this? y I also tried "snapvault release" on SRC, but, it gives me the message of saying that the destiatnion doesn't exist. Also, the volume got destroyed on the SRC, and still exists on DEST. ANYTHING ELSE i CAN TRY, PLEASE?

netappmagic · ‎2014-08-18

The SV relationship of a qtree under this volume is still there, but the volume on both side has already destroyed. What are steps to remove the sale relationship. Appreciate your detailed steps! Thank you!

netappmagic · ‎2014-08-07

I got the part of no issues. I thought it is part of now production data, Isn't? by this thought, won't I remove production data, if I remove base snapshot? I guss, I don't understand what role the base snapshot plays...

netappmagic · ‎2014-08-07

Please let me know what OCUM is? Yes, snapmirror gets updated every hour

netappmagic · ‎2014-08-07

You are correct, this is now the new SRC. So, I have been asked to remove the base snapshot from the new SRC production, I don't know, but, would that cause any issues? and why?

netappmagic · ‎2014-08-07

JGP, I have migrated the volume to another filer (not DR dest), so, I no longer need the original production filer now. The problem is now bt the origianl production filer and the new production filer. So, I can not resync the src, since it has already been abandoned. I might be missing sth, in order to get rid of "broken-off" line, as suggested, I need to delete base snapshot on DEST. By removing this destination, would that cause issues on now production volume?

netappmagic · ‎2014-08-07

Yes, snapvaulting off a SM destination. So, could it be caused by a locked snapshot on the SM destination?

netappmagic · ‎2014-08-07

I can not do re-initializatoin, since the SRC has been or should be abondoned. If I understand correctly, re-initialization would damange the data on SM dest which has been in Production already. I am still no so clear, if I remove the base snapshot, would that have any impact on the Destination(primary Production now)?

netappmagic · ‎2014-08-06

My 2nd question is , if I remove the base snapshot, Do I then have to run the baseline (initialization) again? I thought the baseline will create the base snapshot.

netappmagic · ‎2014-08-06

when I run "snapvault update src:src-tree", I am getting thefollowing error "Transfer not initially successful, Retrying Monitor progress with "snapvault status" or the snapmirror log" Immediately if I run "snapvault status", it shows me "pending", then quickly becoming "idle" again Could you please tell me how to fix the issue? what should I do now to update SV? Thank you in advance!

netappmagic · ‎2014-08-06

If I remove the snapmirror base snapshot, do I have to rebase it? HOw do I distinguish SM snapshots, and none-SM snapshots?

netappmagic · ‎2014-08-05

Right. I know it'd remove the line by removing snapshots. However, as I said, the destination is already in Production now. Would it cause any issues if I removed snapshots on the destination? and should remove all snapshots including the base? Looking forward to hear you again.

netappmagic · ‎2014-08-05

I have successfully migrated a volume from source to destination filer. Then after that, I did quiesce and break, as well as release (from the source). However, the SM relationship is still there and shown as "broken off" after I run "snapmirror status" . How do I remove this line? there is no definition in /etc/snapmirror.conf. I can not remove the base snapshot on the destination, because it is Production now after the migration. Please help me out!

the file system and along with the long options already in /etc/exports file. After I made a change, I want to re-export the entire entry, including options, but without typing the long options in the command line. Since the entry is already in the file, and -p will add the entry in the file, so -p could not do the job. hope it is more clear this time.

netappmagic · ‎2014-05-29

I wante to export only a file system with all options specified in /etc/exports, I can use the command exportfs -io [options] path. However, since there are long options come with that path, I am wondering if there are any ways, I can only specify the path in /etc/exports, and don't need to specify the long options. If I do exportfs -i path, it will export the file system, but all options get cut off. Thank you!
