Media stuck in drive

Hi,After a power failure the tape library is showing offline with the error initializing device failed. I restarted the Commvault server and the error went away however the drive is showing a media but in actuality it is empty. I can’t mount a tape since Commvault thinks there’s still a tape inside the drive. How to resolve this issue?

How to move data from LTO4 (from one Tape library) to LTO7 on another Tape library?

Hello,I have old Tape library TS3200 with LTO4 tapes and new Tape library HPE with LTO7 tapes. I would like to copy data from LTO4 to LTO7 tapes.I worked according documentation Media Refresh (commvault.com) .I have Enabled Media Refresh on Storage policy copy, media for Refresh I have marked Full, and Pick for Refresh. I have run Media Refresh job and choose tab Start new media…No, I have error “There are not enough drives in the drive pool. This could be due to drive limit set on master pool if this failure is for magnetic library.”I don’t know where the problem is?Is there anything else to do for Media refresh operation?Best regards,Elizabeta

Stream allocation for Auxcopy

Could someone explain a flow of process for allocating readers for an auxcopy job?What does stream allocation take place in CVJobReplicatorODS exactly? I see that the number of readers is a function of num of CPU and RAM. By default, each CPU in a proxy can support 10 streams, and each stream requires 100 MB of memory. For e.g for VSA.E.g. My VSA backups were backed up with x number of readers and y number of writers to HPE StoreOnce Catalyst.How does the replication agent (auxcopy) decide and allocate readers for copying a list of N jobs to tape. Imagine there is a primary copy → Storeonce Catalystsecondary copy → tape (combine streams to 2 tape drives with multiplexing factor of 25). Number of readers varies from 12 to 38 in my environment. It appears that the number of readers used for the subclients plays a role in the number of readers that will be assigned in the auxcopy. My goal is to increase the readers for the auxcopy jobs for improving the performance. My auxcopy with 38 rea

Data Written vs Size on disk (HyperScale)

Size on disk 55,74 TB, but data written is 24,77 TBHi folks,I’m trying to figure this out for few hours and I still didn’t find anything wrong in the Storage Policy, DiskLib, Media Agent properties... Backup jobs are also fine. I have counted 10800 jobs manually, just to be sure that the size is correct. 24,77 TB of data is written. BUT how it can be possible, that size on disk takes 55,74 TB?Did someone had the same situation?

Auxilary Copy not copied some jobs

Hi Folks,I have interesting situation about aux copy. I’ m doing DASH copy from one Disk Library to another Disk Library. Despite the successful completion of Aux Copy, 4 jobs remain in "Partially Copied" status. I ran Data Verification on Primary Copy for 4 Jobs and it completed successfully. I did Re-Copy but it stays the same, I did Do Not Copy - Pick for Copy but it's still the same. All Backups is selected in Copy Policy. What should I check?Best Regards.

Mount path to Mount path Data Migration

I need to check if there is any option to move the data from one mount path to another mount path in the same library. I need this to be done for mitigating over commit issue at back end storage. I am having 3-4 mount paths in which only one job is there , i want to move that one job to any other MP within the library and get that deleted so that over commit issue will get solved.

S3 Compatible Storage Untrusted Certificate

Hi! I’m trying to add S3 Compatible Storage as a Cloud Library, but I get error: 3292 1194 12/20 10:31:44 ### [cvd] CVRFAMZS3::SendRequest() - Error: Error = 440373292 1194 12/20 10:31:48 ### [cvd] CURL error, CURLcode= 60, SSL peer certificate or SSH remote key was not OK I already troubleshoot it and I was able to successfully add the storage as a Cloud Lib using “nCloudServerCertificateNameCheck” mentioned in another thread (Thanks @Damian Andre ! ) The thing is that the provider has a valid certificate Issued by:CN = R3O = Let's EncryptC = USwith root cert:CN = ISRG Root X1O = Internet Security Research GroupC = USSo I am wondering if instead of ignoring all the possible certificates I could just add this one, valid certificate to Commvault so it trust this provider and allow me to configure DiskLib. Is this possible? Also not sure it that’s related since certificate administration is not my cup of tea, but curl-ca-bundle.crt is dated to FEB 2016 on this MA which is a fresh in

System Created DDB Space Reclamation schedule policy

Hello,after upgrading from V11FR20 to V11FR24 I noticed a new schedule policy named “System Created DDB Space Reclamation schedule policy” which was disabled by default.I basically know what the Space Reclamation functionality is about, and the policy has all our deduplication engines assigned. But when initializing this policy it finished in less than a quarter of an hour and from the logs only one dedup engine was processed. Another manual start just gives below error message. Can anybody explain to me what this schedule policy is about and how it is supposed to work?

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?

Chunk and Block Size for Cloud Libraries

Hello all,I am trying to find some specific guidelines for Block and Chunk settings when related to Cloud Storage. The information I have found is generally related to Disk and Tape Media.I have been reviewing an environment that uses Chunk settings of either ‘Application setting’ for Primary Copy and a mixture of ‘Application copy’ and 4096 for secondary copies.Block size has been set to 1024 and in other cases set to ‘use media type setting’.I am wondering what the best practices for these settings are and if any of these user set settings are overridden?

Hi, I’ve an old sealed DDB with no more jobs associated to it, it only shows some number of unique blocks left ( for a size of 1,18TB ) , secondary blocks is 0 , application size is already at 0. How can I then do what you proposed to do: “then remove ALL of the blocks for that store in one big macro prune.”?Cause I’d like to get totally rid of that sealed DDB ?

Create a tape job for new full backup

Hello,I need to create a backup job with all full backups to tape in a physical library(new library) that the customer has purchased.Today all backups are on disk (File Library).After the new Jobs to tape has been succesfully executed (3 backup jobs to tape will be done), i need to erase the full backup, which today is very old and needs to be done a new full backup, because the size will be smaller and will free up more space in disk.Wait guys for the best practices to do this.Another question: i will create the Storage Police for the library with permanente retention and include all tapes in the same SP or create other for example: Database, Exchange, etc.@Mike Struening

AuxiIllary copy slow and architecture review

Hi, Everyone. I have a customer with this exact problem. After the Commvault refresh/reconfiguration which was concluded some months back, we had some issues backing up to tape which we finally understood was related to the tape drives we were using then. We have resolved the issue with the drives but we are still having copy to tape running at a very low speed (As low as 13GB/hr). Kindly assist us with below. We have sister companies running this same Commvault and we want to know how their setup is different from ours that make them better. We need to review our architecture to be sure the copy to disk and copy to tape can happen at the same time from the primary source. The difference in storage in terms of I/O and disk rpm from what we have here and that of our sister companies. Is there any way i can help them, please?
