Hi everyone,I have a question regarding the compatibility of HPE StoreOnce Catalyst with an air gap storage solution.Current Setup:HPE StoreOnce - Currently configured as the primary target backup storage and a Catalyst storage.New Addition:HPE DL380 server - Intended to be used as air gap storage.Question:Is it possible to utilize the new HPE DL380 server as an air gap storage solution while maintaining the existing HPE StoreOnce Catalyst as the primary backup storage? Thank you for your time and assistance.

Hello Team, Hello,I have good experience on Commvault environment upgrade but I want some advices about HSX environment where I a not very familiarCommCell version is 11.34.47 End of life target version is latest 11.36Current HSX Clusters info :whichCommit.shBranch: QBD[v-5.0.8.2]rpmhedvig-common-5.0.8.2_3820_f13a4ee0db-1.el8.x86_64hedvig-cluster-5.0.8.2_3820_f13a4ee0db-1.el8.x86_64In a standard environment, I update :1 - Commserve Linux PROD2 - Commserve Linux DR3 - Media agents one by one, and I connect to each media agent to perform the update locally not push4 - Access nodes5 - Index cache Servers4 - update clients I thing for HSX environment it is the same order :1 - Commserve Linux  PROD2 - Commserve Linux  DR3 - HSX Cluster 1 3 - HSX Cluster 24 - Access nodes5 - Index cache Servers4 - update clients My question is about HSX Clusters update.

We can no longer do any backups after a “minor” upgrade.I upgraded our Commserve from 11.34..47 to 11.36.39.  After it was finally done and rebooted, etc. Commvault thinks that the address of the Commserve changed and doesn’t agree with the license file. Nothing changed regarding DNS or networking.  Control Panel->Licensing and Registration shows me the correct address next to License IP Address but shows a completely incorrect address next to CommServe IP Address.For example (with made-up addresses):CommServe IP Address:  10.1.1.50   ← This is actually the addresses of one of our clients, not the CommServeLicense IP Address:  10.1.1.10  ← This is correct and is the machine I’m logged on toWe have always used the same IP address on the Commserve system as specified in the license file.

Hi together,currently we have an issue with a to high number of DB2 log backups. We are approaching more than 20K jobs each day.The threshold for log backups is set to 2 (sDb2ThresholdALFN) due to the requirement that almost no transaction log information should be lost in the case of a desaster.This setting creates a very high number of jobs in Commvault.For HANA we can use the persistent log backups … i.e. Commvault creates one job that is running for 6 hours and is collecting all the log backups in this time period.Is it possible to use something like this for DB2?Regards.Michael 

Hi, we seem to have failed job on backup due to an error Description: Error opening the disks for virtual machine [XXXX]. Verify that the correct transport mode is selected. Error: SecureChannelFailure (Unable to read data from the transport connection: Connection reset by peer.) See http://kb.commvault.com/article/63206 for additional information.Source: xxxx, Process: JobManagerwe followed the KB above but already set to Auto we tried couple of other solutions to no avail . Any suggestions as this has been running smoothly . our other site running on same config . All i did recently was changing MTU size for our hyperscalers . But this is done for other intact site . This one seem to have been effected and not sure what other thing to look for   

Hi, I initiated Change index server job for one client(which has big indexDB). The job was running for a long time with no update.I want to suspend and resume. I attempted suspend. Post that the job shows suspend pending. Right click does not show kill option.I tried force suspend but no luck. I tried to use qoperation to kill.It gives the error message the job is in suspend pending and cannot be killed. Please advise how I can kill this job forcefully without recycle of CV services on Commserve.

Hi Community,our customer use IntelliSnap Backup for the Sybase Databases. Now the customer has told me that the full backups are not logged in the DBA Cockpit.Only the Log backups. I assume this is because a classic streaming backup is performed for the log backup.Is the following backup copy required here so that the full backup is also entered in the DBA Cockpit?https://documentation.commvault.com/2024e/expert/sybase_intellisnap_backup_copy_operation_overview.html#dump-based-backup-copyThe IntelliSnap backup cannot be stored in the DBA Cockpit because it is not a classic dump, right? Thanks and best regards,Andreas 

Hi Guys, i have Quatum scalar i3 tape library, which is connected to the MA via 8 GB FC link. The library has one LTO 8 drive and also the Active Vault licence. what i want ? every friday synthetic backup to tape - i have dedicated 20 LTO8 media in Online, Partition, after backup the media will be exported to the offline partiton in the library.  every day bigdata index and DR to the another for example 2-4 media, these media will be online in library and not exported after backup to offline partition, because DR and indexes use only about 20 Gb per day and LTO8 has 11 TB = wasting of tapes. How to configure it ? any advices ? 

Hi Experts , I have been  task to migrate data from 7 years retention Tapes to our new store once catalyst stores library.The original tape library is already no hardware support and broken and it is also in a different CommCell. after merging the CommCell clients. I am able to see the Tapes storage policy copy ( the primary copy is on a disk storage which is also not recoverable any more.) I am thinking to use aux copy but from  console it seem I can only copy the tape to another tape using the new tape library on loaner for migration purpose by HP. Is there a way to use the loaner tape library read the tapes and direct copy to the Store once catalyst stores?

Hi team,Trying to undesatnd, how commvault uploads the job metadata. Came across an error “Unable to upload job metadata to the remote file cache” and the client is trying to connect to the failover commvault server. Is the metadata upload location configured automatically or we have an option to point to any specific commvault server? Thanks in advance ! 

I have a number of appliances running suse linux 12 needing file system backups.

Is there a way to control which nodes Commvault uses as a SQL backup master in a SQL AG backup?We are doing a migration of our SQL AG servers to another Commcell but the approach is per site. So they are  moving the primary replica first. What I would like to know is if there is a reg key/ additional settings to enable to force Commvault to assign the SQL Backup Master on the primary replica.  From what I know Commvault chooses the SQL Backup master at random. Any useful suggestion is appreciated.

Hello, I need help in diagnosing whether a copy of Big Data Apps is needed and why it started executing. I noticed it after one of Commvault's updates. Client is “Storage policy name” plus _IndexServer ex. 2w_prod_IndexServer

And if it is needed for all the time regardless what type of backups are running?

Hi Communitydoes anyone have a custom report they are willing to share that shows only synthetic_full backups that have failed in the last week?More specifically i am looking for a report that outputs just a list of servers with failed synthetic jobs over that last week. nothing else.with the standard reports it shows all sorts of information, like generated on date, or report criteria, and all sorts of details that makes it very difficult (not to say impossible) to convert into a ticket.

which is better. Which commvault does the encryption or does the storage do it?

HiIs there a way to have commvault re-order the sequence of tapes in a library eg move the lowest sequence barcode to slot 1, the next to slot 2 etc

Did a vmwarebackup (vCloud director 10.5) yesterday on a new server that has windows server 2019 and sql server 2019. During the backup (app consistent snapshot), commvault did not report anything wrong with the backup job what so ever.But in the OS, all disks except c drive was lost, they where still visible in vmware but not in the os and rescan in disk management did not work.Event logs was not very informative either other then “unexpected error” messages from sql.System writers reported no errors on all expect “system writer” that reported [5] waiting for completion and SqlServerWriter reported [8] inconsistend shadow copy.And still after i killed the job and the snapshot was removed, there were no disks showing up but after a reboot they were back.The vm it self is up to date on hw version and vmware tools, windows updates is also fairly up to date. I have been around long enough to know that it is i that needs to figure out whats wrong since from the vmware admin perspective thi
