Max number of Simultaneously Mouted HotAdd Disks PVSCSI on VSA Proxies

Hi everyone,We are currently deploying a Commvault environment to protect via VSA a great amount of VMs (almost 6000VMs)VSA proxies are Windows Server 2019 SE VMs that reside on the same cluster that VMs we would like to protect. So transport mode will be HOTADD.We are currently on test phase so as to obtain results and determine the number of VSAs Proxies that finally we will deploy.The environment is the following: Commvault version: v11.24.7 VCSA: VCenter 7.0u2 ESXi Version: 7.0uw VSA Proxies O.S: Windows Server 2019 SE VDDK version used on Backups: 7.0.1As per VMWare documentation says on VMWare 7.0u2 each PVSCSI card on the proxy VSA should be able to mount 64 vmdks of the Backed-up VMs.The issueis that we are monitoring during the backup and each proxy is just able to mount 15 disks via hotadd (stucked on the previous limitation of VSphere 6.5)We have added manually more than 20VMDK disk on the Virtual Machine so we understand that this is not a VMware issue. The limitation arise

Disable VSS application quiescing using VMware Tools

Hi, If a VM has the setting to Disable VSS application quiescing in VMware Tools, will this affect the VADP initiated quiescing through CV VSA backup? Will it at all affect the Filesystem and Application Consistent (quiesced) data protection operation?/Patrik

Unable to login using predefined root and password to FREL

I was deployed FREL version CentOS Linux release 8.2.2004 to my VM lab to test prior to deploy it in our prod environment. The root password was predefined during the OVA deployment but upon login to i was not able to login successfully using my root password. Why is that happen? is there a default user that i can use to change the FREL root credential?

VM Socket License not releasing

Hi,We had a backup of a virtual machine that backed up on a host that wasnt included in calculations for VM Socket licensning. I have moved the virtual machine to a host that was included in the VM socket licensning and have taken an incremenmntal and Synthetic full (which in job properties show as being on the hypervisor host i expect) yet the VM Socket licensning is still showing as using a VM Socket license for the “extra” host.This has been the case for a few days so licensning would definitely have been refreshed.Any help to release this licnese would be appreciated.Thanks

VM backup failed - VM is not in a connected state

Hi there!I would like to discuss the following backup job issue. There are some VMs, that failed to be backed up due to the failure reason - VM is not in a connected state. In fact, these VMs are powered off in the vcenter. I was looking for how to cope with this type of issue, but I didnt find any relevant resources.So, my question is how to deal with this situation. The VMs should be powered off, but backups should be running as usual. Is there any workaround in the CV?

Full VM restore with original MAC address ?

Hi,Last week, I restored a full VM whose IP is DHCP assigned, but fount out that, after the restore, its MAC address was changed.According to support, it’s normal because the MAC address is assigned by VMware, so, unless the original VM was deleted prior to the restore, VMware would always assign a different MAC address to the restored VM.The issue is, users who ask for a VM restore don’t usually want to delete the original one prior to the restore, not until they check the restored one to see if it works…Strange thing to me is that, in Netbackup, when I do a full VM restore, the MAC address is not changed, regardless the original one is present or not… So, I just wonder if there is a hidden switch somewhere in the restore setting that does the trick ? Or it is indeed the case that Commvault works differently to Netbackup in this scenario ? Thanks,Kelvin

VSA backup via SAN runs very slowly

We had to move the VSA backups to the second data center because the backup storage in the first data center filled up and we can't delete any data. Since this has been moved, the whole thing has been running very slowly. Transport Mode is still SAN but it only backs up one VM instead of 15 at a time.You can clearly see the throughput between SP_Alsterdorf_Standard and the change to SP_Norderstedt_StandardBoth media agents are set up so that both can access the backup storage and the production storage. Does anyone here have a quick solution to this problem? Kind RegardsThomas

Hyper-V VM restore browse displays duplicate drive letters

When I browse a VM for “guest Files and Folders” (file and print server) from Hyper-V backups I see duplicate drive letters. The VM has 14 drives. This changed after a certain date and only occurs for 1 specific client. The other 2 VMs (also FnP servers) are okay. Drive letters are as they should be.Drive letters are C, F, G, H, I, J, K, L, M, P, Q, R, S, T, but when I browse for recover, I see C, C, F, F, G, G, H, H, I, I, J, J, L, L. The contents also do not match. E.g. when I browse both Cs display contents for the actual F drive.If I browse the “Virtual Machine Files” I can see the correct drives (vhdx files) listed.I have tried from different copies, but all are the same.1st copy is a snap, 2nd is backup copy and 3rd off-site copy. Any suggestions would be greatly appreciated.

Throughput Issue with VMware snapshot backups

Team,From last 2 weeks we are observing performance issues with Vmware snapshot backup over SAN mode.vMware backup jobs are taking 2-3 days to complete , throughput has declined from 1 TB/hr to 50 GB/hr.The underlying backup library is healthy with no disk failures .I see in command center health report that disk pruning status as critical for global vmware deduplication policy . data aging is running on daily basis .How can i manually run pruning of DDB ? Is there any impact on running backup while pruning DDB manually. There is an option to validate and Also , what does Read, write and network % means in Average throughout which is very low .Average throughput 64.27 GB/hr(Read: 14.19%, Write: 0.83%, Network: 84.96%)Regards, Mohit

VM backup size is pretty large

We had a customer who did not make any changes and all of a sudden their backup size had almost doubled; the backups are configured using Commvault VADP. We host the VM in a shared VMWARE Cluster for them. I think they added only one addtional VM and the backup size increased in all the VMS The customer was really concerned with this high bill as we bill them on Backup size; I was looking online and found that this could happen due to thick provisioning and disks are not zeroed and running sdelete utility might help. How is this backup size calculated. I thought if the customer had thin disk provisioning this backup size would be total of what the customer is utilizing however that does not appear to be the case; one of the VM with VM size of 80GB and used size of 40 GB is still showing a backup size of 80GB; so a bit confused; and wondering if we run sdelete would this be resolved or would this reoccur and what caused this issue. Please see the screenshot below from Aug and Sept 20

VMware UUID / duplicate client computers

We just started the implementation of Commvault in a brand new VMware environment. Now I'm seeing already an increased amount of duplicate client computers in our environment causing some administrative nightmares and management challenges.So I started investigating it and discovered the UUID registration to differ from what I'm used to when comparing it to AWS. It appears the registered UUID in Commvault is actually the so called PersistentID/InstanceUUID and this one can't be tracked back from within the VM itself. The UUID that is shown from the OS corresponds to the VMware BIOS UUID. We installed some client agents first followed by the configuration of the VSA agent. Both are being used actively. Fixing duplicate client names is an annoying tasks, especially in MSP environments and I'm puzzled this hasn't been fixed by Commvault. Because when you would use the combination of Commvault client name + BIOS UUID and the name that can be read by the client including UUID than matching

VMware vCenter Enhanced Linked Mode (ELM) Backups

We discovered (the hard way, after doing a restore) that backups taken of vCenters in ELM contain inconsistent data and will likely break ELM replication if they are used to conduct a restore. We worked with VMware technical support to fix our vCenters’ ELM. It was a painful process.See https://kb.vmware.com/s/article/85662?lang=en_us which suggests some limitations of backups of vCenters in ELM. Not an exhausive list.I am wondering if anyone has encountered these limitations and perhaps there is a workflow we could use to conduct an offline backup? This would have to be during a scheduled outage, but it would be helpful to have some baseline clean backups in Commvault as a safety measure. I have opened a Commvault technical support case. I think we need Commvault to request support from VMware to develop an API or fix their broken ELM backup. The other community thread on this topic has an “answer” which is wrong. I can’t update that thread, so I am starting a new thread. For referenc

VM snapbackups with NetApp Intellisnap

Hello Everyone, Newbie alert.Please correct me if I understand this right. Subclients enabled with Intellisnap backups using NetApp array integration will go like this - A job will be triggered and a VMware and NetApp snapshot will be taken and the snap backup job will finish. Then the backup copy operation will trigger which will mount the datastore to the proxy VM through the proxy ESXI (we have NFS datastores and our proxies are running as VMs). The VMDKs will be copied to the library through this operation and it will finish. Now we have installed a new NetApp array and the team is continuously relocating the VMs to the new datastores round the clock. Now our snapbackups are completing but when we are triggering the backup copy operation, that is failing with “Unknown VMInfo error ”. After marking the Job as do not copy and running the snap backup again, we are able to successfully complete the backup copy. What would be the best approach to make sure that our backup copy operatio

Commvault is trying to consolidate the same VM several times

HelloApparently, after successfully backing up some VMs (VMware), commvault is requesting disk consolidation several times in a row (without waiting the first request to finish).This sometimes is causing the VM to be unresponsive. Commvault is being proactive but it is causing downtimes to the environment.1 - can I disable this feature (commvault starting consolidation tasks for the VMs that needs consolidation)?2 - can Commvault skip this VM? I read that commvault would skip VMs that needs disk consolidation. But I am not sure if this is really happening.regards,Pedro

With a vcenter migration to a new vcenter what happens to the job history after the vm has been moved?

With a vcenter migration to a new vcenter what happens to the job history after the vm has been moved? Let say perhaps there is a infinite retention set on job and the vm is moved to the new vcenter, does that job now need to be deleted? Thanks

Removing VMs from subclient and backup

Hi there,I would like to discuss quite a common trouble.I have removed several VMs from the backup - they have been removed from "Contents of subclient" under the subclient properties. However, the backup jobs binded with these VMs cannot be aged due to the basic cycle rule . Even though, the global rule "Ignore Cycles Retention On De-Configured Clients" is set to 1. In fact, the VMs are already deleted from the vcenter (last copy of VMs is retained in the other DC). Moreover, none of these VMs are seen in CV Browser tab. So, is there any option how to bypass the basic cycle retention law and let these backup jobs aged? Of course, I could manually delete these jobs from the tapes, which is a quit unrecommended approach, isnt? Neverthless, it is the last chance to free the tapes.
