Isilon Smart lock as WORM Enabled Library

Hi Team,Iam testing Isilon Smart lock feature for storage level immutability with Commvault  DASH Aux Copies.My Dedupe is hosted on local drive ( non-worm) on windows media agent .Library is created from smart lock directory from Isilon .My question is that how does CV writes to WORM enabled storage ? As per the current settings on Isilon Smart lock there is autocommit time period of 5 mins  ... files that have been in a SmartLock directory for a 5 mins of time without being modified will  automatically committed to a WORM state.Can Commvault handle this because i guess there will be chunks which will not modify for 5 mins and need to update later during Aux copy process? Will the Aux copy fail or create new chunks/folders ?What about DDB ? Keeping DDB on non-worm and data on worm is recommended way ?Regards,Mohit

LTO9 - Media calibration / Characterization

Hi and happy new year to all of you !I would like to know if some of you have already implemented some LTO9 drives / tape libraries, and would love to get your feedback about it using Commvault.My experience on the LTO9 media, using dual tape drives tape libraries, is quite bad.The Media calibration / optimization / characterization phase that any new LTO9 media has to deal with is a pain, on my side.Looks like on the first mount of a media -- let me reword it in my ‘old guy’ words -- it has to be somehow formatted to be able to be used by your favourite backup software. Below a link to Quantum’s FAQs about this :https://www.quantum.com/globalassets/products/tape-storage-new/lto-9/lto-9-quantum-faq-092021.pdf Short calculation : 50 LTO9 brand new tapes may require up to 2hours each of ‘calibration’ before they can be used. So this equals to 100 hours of ‘calibration’ before you could use the full 50 tape pool.. 😱  My 1st issue was that I had to adjust all the mount timeouts in that LT

Media agent rebuild. How to retain disk library backup data.

We have a Media agent MA1 (Physical Server) located at Site A with disk libarary still having jobs under retention till next one year. However, siteA is now decomissioned. We would like to rebuild MA1  and use storage at another site SiteB, but would like retain jobs which are still under retention.  Doing a backup job of CV_magnetic files to another disk library a good option What would be a best approach

Drive in which Media is mounted is not ready to use

Hi all,in the Job Controller there is a waiting backup job due to the following error message:"Drive in which Media is mounted is not ready to use. Advice: Please retry your operation later. If the drive has a stuck volume, reset the drive to recover the media."As proposed, I tried to "reset drive", but it didnt help. The tape seems to be stuck in the drive.Do you have any suggestions what to try next to work it out?

Network Throttling Aux copies

Since the other thread was stated as solved I’ll start a new one. From What I understand the Network Throttling on the media agent only effects backup jobs, not Aux copies jobs bandwidth.There is an option to limit the Aux copy bandwidth usage by setting the Advanced setting "Throttle Network Bandwidth(MB/HR)" on the stg policy copy.Unfortunately that effects the usage all day as there is no possibility to set it per time interval.I have two Aux Copy jobs running for two different Storage Policy copies with the setting for bandwidth limitation set to 5000 MB/HR which is roughly 11 Mbit/s.So running two of those shouldn't use more then 22 Mbit/s.Looking at the Current Through put they are 3,92 GB/hr and 2,97 GB/hr in Comccell console. Those combined gives 6,89 GB/hr roughly 15 Mbit/s. I understand that it's not 100% accurate as the data is deduplicated.But looking at our monitoring I see two streams going to Azure one using 30 Mb/s and the other at 20 Mb/s.In fact the Aux copies tend to

Mount Path move failed

We are trying to move a mount path to a new media agent, but it’s failing ever since we stopped the job. The disk became full resulting the data migration job being stuck for weeks, so we stopped the job and freed up space. However, every time we try to restart the mount path move it fails.We did the following to troubleshoot:Run disk defragmentation Verify disk and mouth path are online Validate mouth path Verify no disk maintenance task is running General sanity checks The error that we get is:Move Mount Path Job Failed, Reason : The mount path is under maintenance and hence cannot proceed with the move operation. Source: <MediaAgentName>, Process: LibraryOperation Can anyone tell how to fix this error? How do we get Commvault to see that the disk is not in maintenance mode?

Auxiliary copy to tape

Good morning to all.On a monthly basis I release auxiliary copies to tape ending with a total of 11 tapes.I wanted to do a restore of about 675MB and it asked me for 9 tapes to do it, is this so why the data has been distributed on 9 tapes?Shouldn't it be on one tape only? Since the size of the L7 tape is large.  Could it be due to the "Use Scalable Resource Allocation" option? Thank you very much for your help.Best regards,Johana 😀

Azure Combined Tier

A customer of ours intends to move their Azure workload to Metallic in the near future.Because we don't manage the azure side of things for the customer, I assumed that the Azure blob storage was a combined tier based on what was configured in Commvault (screenshot below). The cloud libraries are configured in Commvault to use a Combined Tier of storage where we write metadata to Hot and chunk data to Archive tier. Based on that I’d suggested that a rehydration of data is needed from Archive tier to hot tier to perform an Auxcopy to Metallic or lodge a ticket with Microsoft to have the entire contents of the blob converted to Hot tier so that it can be read by the AuxCopy process.  CV cloud library explorer shows chunks in Archive tierTo learn more about Azure's blob storage configuration, the customer turned to Microsoft. Microsoft confirmed that no data needed to be rehydrated in order to migrate to Metallic because they could only see Azure's hot-tier blob storage configured on that

Adding extra drives to existing tape library issue

Hello, EveryoneHow are you, today?I have a problem i am trying to resolve. I don't know if anyone can be of help.So, this customer has a tape library with 3 drives but 5 slots. They had 3 existing 3 drives which is running fine. They just added 2 more drives to be configured. I have been trying to detect and configure the drives but i can see them (it says undetected, unconfigured). It says SCSI adapter has been removed, Please go to property page to select the right scsi. Can you help, please? Eventually i detected and configured one of the drives, but can’t detect the last one. During the detect an configure scan, the 5th drive shows but in the data path and library, it does not show.

MS Office365 and new Exchange Agent, Status of Tape Support

Hi Commvault Community, i would like to see, if anyone else is facing the same Issue. We have a few customer that are still using Tapes to move weekly/monthy Backups to a save location.With the change to “forever incremental” they are now facing a big issue to collect all the backups of the agent on to the exported tape. There is no process to generate a Synth. Full or everything likewise.One customer is still holding on to the “old” exchange one-pass classic agent, so he don’t lose the Synth Full Options.Another customer is manually creating a new Storage Policy Copy every month to get all the Backups on the same tape.We have shared this problem a few months ago, we even had a talk at the GO 2019 with dev. Back then we there told there will be a solution on its way, we could expect it for SP20. Now we are at SP26 and there is still no option for these customer.

Aux Copy size and throughput summary for a given period

Hi Team, We are in the process of evaluating our recent Aux Copy performance to our DR site as we are scoping for future capacity and bandwidth requirements. It would be very useful if there was a suitable report to show me the rate of throughput and the amount of data copied in a summary format, similar to what you see when running Job reports and aligning by Storage Policy (as opposed to client). Surprisingly, I can’t see a summary of the Aux Copy results in any reports.Although the Aux Copy entry in the report shows the data copied, and the overall throughput it is only for each Aux Copy job. You can see below in this example, where we have a few days worth of Aux Copies:-  What I really need is a report with a summary line at the top of all data copied and the overall throughput figure.At the moment, I need to export into CV and then reorganize the fields so I can add things up manually.There is one other report which might also be of use, which is the Jobs in Storage Policy Copies
