Simplivity backup can not run

[sarwoedi]

I have problem when I backup lokal or other cluster. The error message display "session cloning failure".

I checked in federation , all omnistact are alive and try to create vm or cloning vm via vmware is OK.

FYI:  - VCenter appliance 6.5

       - Simplivity omnistack version 3.7.3

      - Hardware HPE DL 380 Gen 10

      - Using PSC beetwen DC and DRC

Please help.

Thanks

Hi Sarwoedi,

Thank you for reaching HPE.

We apologize for the delay in response.

Please provide us the below details

1. Was the local back and remote backup working fine before ?

2. When did the issue occur ?

3. Was there any changes made to the Federation before the issue could occur ?

4. You have said that the VMware clone is working fine. Does the SimpliVity Clone work fine ?

5. Do we have problem only while taking the VM backup. Does other SimpliVity Features work fine ?

6. Is the issue noticed on particular VM/s or on all the VMs ?

7. Have you tried taking the VM back up using CLI ? Does the issue persist even when a backup is taken using CLI ? 

8. Below is the command to run on the OVC CLI:

svt-vm-backup --datastore datastore-name --vm vm-name --name backup-name --appconsistent --datacenter datacenter-name --cluster cluster-name --destination datacenter_name
   
Note: If the backup works fine on CLI. Then uninstall and reinstall the SimpliVity Plug-In

9. How to run the commands on the OVC. Below are the steps:

a. Take a Putty(SSH) to the OVC using the OVC management IP
b. Login to the OVC using the vCenter SSO credentials which is "administrator@vsphere.local"
c. Run the command:

svt-vm-backup --datastore datastore-name --vm vm-name --name backup-name --appconsistent --datacenter datacenter-name --cluster cluster-name --destination datacenter_name

Thank you for writing to us back.

As per the information provided by you, the backup works fine using CLI.

Hi Sarwo Edi,

Thank you writing to us back.

This needs a deep analysis..Requesting you to provide us the serial number of the server in a private message.

You may also upgrade the Federation to the latest version(4.1.3) as the currect version of the OVC is too low.

Regards,

Deepak

Hi Deepak,

Thanks for your info.

The problem is if we upgrade to latest version, we can not upgrade on DRC site, since on DRC site we use Simplivity Dell server not HPE server. These servers can not be upgraded to lastest version. The maximum OVC version for  Dell server is 3.7.3.

Please advise.

Thank you.

[Deepak_K]

Hi Sarwo Edi,

Thank you for writing to us back.

The maximum supported OVC version version for DELL is 3.7.10U1. Hence, the Federation can be upgraded to 3.7.10U1. Please find the below interoperability and the upgrade guide links for the HPE and DELL SimpliVity Servers :
