i am trying to configure intellisnap , storage array is powermax 8000 , and my media agents are hyperscale x nodes , having access to storage via fiber (SAN mode) i was going thru below requirements , if anyone can clarify doubts https://documentation.commvault.com/2023e/expert/system_requirements_for_dell_emc_powermax_vmax3_vmax_symmetrix_storage_array.html1> Solutions Enabler Licensing and BASE/Symmetrix license for all snapshot types - where is this referring , for the storage array or on media agent2> LUN masking records and views must be accessible from the host where the backup takes place. what is the host referring here ? 3> what is client and proxy computer , remote MA referring here , since we are using Hyperscale x nodes we are not

HiI'm not an expert user.After the automatic upgrade job to version 11.28.8, the backup jobs failes with the following error:Error Code: [62:308] Description: The media side mounted is write-protected. Source: backupserver, Process: cvdStatus: Mount ErrorLibrary Name: AutoDiskLibDrivepool: DrivePool(backupserver)1Drive: Folder_03.28.2019_11.26Media label: CV_MAGNETICFailure Reason: The media side mounted is write-protected.Under the library all mount paths have Read/Write AccessProperties for the mount path under Allocation policies are marked Maximum Allowed Writers.Tried manually upgrade to version 10.28.10, but nothing changed.This is a disk library, not tape. The library is about 89% full, but still have about 7,5 TB free space on the given mount path. How to enable read write? 

Hello All,we have Mongo Sharded Configuration backup on COmmvault. We backup it daily full. As you know COmmvault take snapshot before backup and , It deletes snapshots after backup copy. When I check the client on Commvault there is not any snphot presented. But There are many snapshot taken by COmmvault on host. İs it fine if we delete them manuelly or how can we delete them? Commvault should delete them automaticly right? Snapshots on host: [gbmnsp08]~#lvsLV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convertcvnv_1213025853 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_1615395985 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_2032137259 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_2251453908 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_2532432752 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_3191856748 datavg swi-I-s--- 50.00g lv_data01 100.00 

Hi CV Experts,  We are on 11.32.59.As per default schedule DDBVerf configured in our environment. It is selected as Quick verification.But in 11.32 documentation, it is mentioned default schedule to run with “verification of existing jobs on disk”. https://documentation.commvault.com/2023e/expert/verification_of_deduplicated_data.html Kindly note,we have 1PB of data, so running ‘verification of existing jobs on disk’ shows estimated time to complete as more than one month.Can we run default schedule with Quick verification.Does it identify the corruption or missing in chunks on storage ? https://documentation.co

Hello World, I’ve recently replaced my media server and noticed my auxiliary copy jobs is getting this error whenever i try running the backup:User specified a data path which is not part of the data paths in the storage policy copy. Advice: Please specify a job data path which is part of the Storage Policy copy. Can see that the new media server has access to the library, but not sure what else to check.

Hello everyone,We still have some questions regarding IntelliSnap. I’d like to confirm if auxiliary copies made with IntelliSnap always use SAN and what requirements are needed to enable this functionality.We appreciate your assistance. 🥺🙏🏽Thanks in advance!

Hello everyone,I have a question about changing the Media Agent where I have configured DiskLib using to this the disk from my array.Now I want to refresh the MA to a new one. Could I for example move DDB, Index to the new MA and then reassign the disk from the old MA to the new MA and it should work fine or is there another way to do it more securely

I am experiencing significant delays with my backups despite having a high speed internet connection and no antivirus interference. I am unsure what might be causing this issue and would appreciate your assistance in identifying the cause.Could you please guide me on the best steps to diagnose the slow backup performance? 

With the Big Data Apps Indexes that write to tape, what happens if the storage Policy is changed to write to disk ?  

Hello Experts, We are in the process of replacing the Storage of primary backups and would like to take expert opinion before proceeding further. Our storage policy have StoreOnce as a primary copy (retention 30 days) and Tape library (retention 10 years) for the secondary copy. Going forward we want to replace the StoreOnce with Hyperscale-X for primary copy. The data on StoreOnce is copied to tape and we want to leave the StoreOnce for next 30 days to allow the data to expire. Now the questions are If we modify the storage policy and replace the StoreOnce with HSX, will we be able to restore the data on StoreOnce in next 30 days if required? If we create a new storage policy, how can we move the catalog of Tape from old policy to new policy? What is the best approach for this ?Appreciate your suggestions on this 

Hi Commvault Community,I am writing to inquire about releasing space on a storage unit previously used for backups. Here is the context:The library was configured on a QNAP unit as a network shared folder. A Storage Pool was created for the deduplication database, and a Storage Policy was associated with it. All three elements (library, Storage Pool, and Storage Policy) have been deleted to clean up the shared folder. However, despite considerable time passing, the storage has not been freed up. Manual deletion of the folder contents is also not permitted.Steps Taken:Deleted the jobs in the Commvault console, but the shared folder still shows "Size on disk." Performed data verification and Space Reclamation; however, no storage was released. Deleted the deduplication database, but the folder information was not cleaned up. Attempted to manually delete the folder contents, but security permission

 Hi Team,According to the info below, I would expect Commvault to create a new DDB Store for the Database, but it did not. Are there any other criteria that are not matched for creating a new DDB Store? Any idea why this might be? Is there a way to manually create a DDB Store for the Database? Version: 11.32.65

Hello, I’ve logged a case at Commvault support but.. they’re reviewing logs.. (🙄)https://support.commvault.com/Case/Details/241010-316 (for those that would have access to the case to spot the details of the issue).On a linux physical MA, with of course dedicated NVME disk properly setup with the lvm to have enough spare space to perform lvm ‘snapshots’ of the DDB volume, one of my MAs got a stuck DDB backup job during the night.The ddbbackup job has been killed (😏) and even restarted later (🤐) and as it was not working again server was rebooted, before another ddbbackup attempt was initiated. Of course, it failed.Then, I was called and looked at the problem, and (my gosh, sorry for that) CHECKED THE LOGS of the job… Right away I spotted that the ddbbackup was stuck upon querying ‘vgdisplay

My customers CV server has some hardware issues and OEM suggested to format the complete server.Now, There are only few NAS boxes whose old data they want to preserv and rest they can take backup from scratch and all those NAS boxes have a common Storage PolicyNow what is best way to achieve this?Assign LUN to Server Create new Storage Pool with a new DDB ? ( can we assign exisitign DDB to new pool?) Setup Secondary for this storage policy to new Storage Pool When AUX job is completed , take DR copy and deattach LUN. format server Rstore DR then how to brigngf back data from secondary copy..i am confused from herePlease suggest any other alternate method if possible  , NAS has huge data in TBs hence we do not want to start full backup.

HI,I encountered the following error as shown in the screenshot when performing drive cleaning. May I ask how I can solve this problem? Thank you. 

Do we know where in object path is a job UUID?If whether we have any control over what UUID is used or is it completely random? 

we migrated our file server around 30 tb which was backed up using windows server file system agent to netapp FS , what will be the recommended way to protect the netapp FS , if i add the storage array and taking backup does it increase the storage utilization ? will the dedup work which was taken using with file server agent , or ndmp without storage array added will be better 

What is the easiest way to copy data from a LTO 4 tape to a LTO 8Both libs are availablePlease be so kind and provide a step by step manual
