Cloud storage adding and troubleshooting

Hi there,I am trying to add a new cloud storage (S3 compatible), however I am unable to do so. Moreover, I don’t see any asociated log files. I only see this error message:“Failed to verify the device from MediaAgent [xxxxxx] with the error [Failed to check cloud server status, error = [[Cloud] The server failed to do the verification. Error = 44037]]. “ My question is: Which logs should I add to Logging setting? And how to troubleshoot this stuff in general? PS. As workaround I used this - https://documentation.commvault.com/commvault/v11/article?p=51230.htm but it didn’t help. Thanks for any ideas

Which library holds pending delete records

Hi Team, When we have multiple libraries associated with a GDP, then how can we identify which library is holding the ‘pending delete records’ and ‘Data size to be freed’. Thanks,Harshavardhan.

Can't lower reserve space in Commcell console

Hi, I came into work and noticed dozens of jobs in a waiting state due to the mount path not having enough free space.  I am aware that we need to add more storage and we are going to, but in the interim I tried lowering the reserve space from 6TB to 2TB.so that the jobs can finish, and I also see what can be cleared.  It’s not letting me change it.  It will only go to 5960 GB.  I currently have a ticket in with CV. 221017-401. Is there a way to fix this?

How to Reduce Random Read Load on NL-SAS Storage Arrays?

Hello,We are seeing a very large random read load on our Hitachi G350 backup storages with NL-SAS disks. These random reads are completely consuming our backup storage performance. We have two G350s on campus and a third at a remote site. Commvault runs copy jobs between these three G350s.DDB is on NVMe locally in the Media Agent, also the Index Cache Disk.We ran several analyses and Live Optics showed us that the daily change rate is 334.9%, which is mainly due to the Windows File System policy, for which we see 2485.1% daily change rate.Does anyone know how the random read load could be reduced since our disk backup is otherwise unusable. What steps could we take to optimize the Commvault configuration?Screenshot: Thanks for your help!

Can I have two aux copies to the same tape library?

We have a tape library with two drives, Is it possible to have two secondary copies aimed to this same tape library and to start two auxiliary copies at the same time? My desired goal is to have at final two tapes with the same data so way to keep one of them on another safe offsite location.

WORM on VTL

Hello Expers, Recently, customers want to apply WORM function to VTL storage in order to respond to ransomware issue.I searched BOL and the Commvault community, but I could not find a guide on how to configure and operate in detail except for WORM media configuration.https://documentation.commvault.com/2022e/expert/10496_worm_media_configuration.htmlI hope I get detailed guide information for implementing WORM function in VTL or Tape Library. For example, once the WORM media is fully used, It is moved automatically to the Retired Media pool.https://documentation.commvault.com/2022e/expert/10493_worm_media.htmlAnd then is this media reusable? If possible, through what procedure can it be reused? RegardsKim KK

Unusual performance drop detected in pruning

Hey good people at CV!We are getting hourly “Unusual performance drop detected in pruning” event viewer events.I have noticed there was a hotfix here: https://kb.commvault.com/article/77146 , however it seems that 11.28.10 is the currently installed version.At first glance and after reading a few threads here concerning the same issue before posting a repeat topic, I figured it might work itself out.Is there anything else that can be done? Just trying to be proactive.Here is the message to follow, and there seems to be a single Job Record to be Deleted when viewing the DDB Pruning Performance Anomaly Report.Unusual performance drop detected in pruning for following deduplication databases due to increase in (CommServe Job Records to be Deleted)Thanks in advance!

Moving long-term backups to another library

Hello all, is there a possibility to move the saved data from one library to another ?We have two full backups on which we have set the retention until next year. The rest of the backups continue with the normal retention of 30 days and 4 cycles. However, I would like to move the backups that need to be retained until next year to our object storage. I have already prepared the connection to the object storage. I just need to know how to move the data.  Kind RegardsThomas

New DDB stores gets Auto-created.. Horizontal scaling enabled..

The other day I noticed a Critical item in health dashboard under DDB backup section stating one of the store isn't protected.. Noticed the DDB store itself got auto created a day back keeping the old one active..  I noticed this across various environments where we have multiple DDB store with different ID gets created and all of them are actively used.. Couldn't find any documentation that explains it.. It would be helpful if someone throws some light here.. Thanks.. Below is the one i was referring to where DDB store 72 got auto created and if you notice for FS and DB agent store we have multiple ID’ present...

DDB Verification not completing in time

Hi,I’m working on an issue with DDB Verification on a HyperScale X environment.I talked to someone at Commvault Support who explained that planned DDB verifications were removed from the best practices on HyperScale X because it could impact Space Reclamation Jobs, aswell as impact performance. However, our customer needs to be able to produce reports to document and prove compliance in regards to ISO certifications. They were able to import a report on their Private Metrics Reporting server so they can generate reports based on Admin jobs.However, they are noticing that DDB verifications are taking a very long time and they aren’t actually completing, so all subsequent DDB verification are just queueing up. The DDBs in this environment are very large.Does anybody have a suggestion how we could solve this issue and actually getting these DDB verification jobs to finish in a timely manner? Would scheduling them more often solve the issue?Looking forward to your suggestions.Jeremy

Merge mount paths?

Hello,I’ve some older data at one mount path and want to move it to different host where new storage has been already configured and it’s up and running. Is there a way to somehow merge the data from old MP into new one? So I want to move data from Host1 - “D:\MP1” to Host2 - “D:\New MP” to keep everything in single place. Simple move is enough?

MA GRID setup | potential

Hi,  Do you have a best practice how to utilize media agents in a GRID format?For example we have 4 MA’s and let’s say 3 subclients..1 sub client always uses 1 MA (more vsa proxies within the job for vm’s) for VMware backups. So there is a some sorting mechanism for other 2 sub clients to either receive idling MA’s to start the backup, or use the one which is already used by sub client 1… But is there an option to utilize the potential of a GRID solution where we can use more than 1 MA for a backup of a sub client? Hope it’s clear of what I am trying to achieve.

Migrate a Data Path

Hi, we just started to use an object storage to tier out the data after 7 days. We created one bucket and added it to commvault as backup target. Den we changed the config and created another bucket but forget to delete the first one and now commvault is using both buckets to store the data. How can I migrate the already stored data in bucket 2 (data path 1) into bucket 1 (data path 2) ?After I could migrate the data I would like to delete the second data path and then remove the bucket in the Object Storage.RegardsThomas

Unable to add network disk storage

We have CV 11 .24.56 and using Dedupe.  We already have this Disk Library setup and were using 60% of the library but now we wanted to add another mount path and use the other 40% because no one ever used the storage space!  I cannot send screenshots so I will try to explain. We have a Primary site (Pri-1) and an Alternate site (Alt-1) and Commvault copies the data to the Pri-1 Disk Library and then we do a Dash Copy of the data to the Alt-1 Disk Library so we have 2 online disk libraries one at each site and the libraries each have their on Folder or Mount Path and we have Global Dedupe policies one setup for the Pri-1 Library and another Global Dedupe setup for Alt-1 Library. (This is how it was setup by installer).   My issue is that when I went to add the extra storage I was able to add the storage as a new Disk Library with a new Mount path successfully.  The libraries show up in Commvault as Alt-2 and Pri-2 under the library.  I then was able to add this second  Primary Data site
