Restore a VM from a snapvaulted datastore fails to mount via NFS

[PHILIPPE_MESLINOBS]

Hello

I have an issue with oncommand to restore a VM.

We backup with oncommand datastores residing in a vfiler.

the snapvault relationship is done from vfiler0 to vfiler0 as a backoffice task. the destination volume is owned by a vfiler because of customer access.

When we intend to restore a VM, Oncommand wants to mount the cloned qtree, but only via the default admin interface

Dataset:

BackupVM_G2_t1

Job Description:

Restore 1 members for dataset BackupVM_G2_t1 from backup 100.

Event Description:

Host Service:

fcernsvsccust02.cust.fce.lcl

Error Message:

fcernsvsccust02.cust.fce.lcl: OnCommandHSVMware: hsRestore2 bec36803eeeafbecf879cee2996951e6: Error mounting 10.1.119.226:/vol/clone_26685e3e701646ff92663c2947a46c4d/sv_qtr_cust_001 as datastore 9c70bb0f-a794-4b8c-baf3-d3fc3df81e78 to fcernscustesx10.cust.fce.lcl. Check the vSphere Client for any error messages.

we played with preferred address, no way

any idea?

The IP referenced is the e0M management interface.  In our design, we have designated separate VIF's for Storage Interfaces (CIFS,NFS,iSCSI), each interface is either firewalled or is a non-routable network, as is the case for our NFS Storage Networks for our Virtual Infrastructure.  Only management functions and therefore communication flows are able to connect to the e0M Management interface. 

1. To my knowledge, the preferred interface is used in QSM and VSM.  I don't know if there are other Settings\Options available to specify a preferred interface for NFS or iSCSI Mounts.  Without havings some way to specify an interface to use, VM Restores will not function in our environment.

2. Does the nfs.export.auto-update have to be set to On for DFM\Host Services to be able to function?

3. If we are using multiple interfaces, do those interfaces have to be accessible by DFM\Host Services so that DFM\HS can communicate through the interfaces using SNMP\HTTPS\NDMP?

Thanks,

Abe

Please open a support case and request it be attached to bug #580933.

OnCommand Unified Manager (Host/Core) is unable to successfully restore a virtual server backup when the OnCommand UM Core server cannot reach the NFS export where the datastore resides.

Hello Kryan,

We found the issue. The volume we want to restore a VM from is in a vfiler. And in Oncommand 5.1, there is a limitation. in a vfiler, NFS mount by an ESX (via Host package) can only be mounted on the same interface as the primary address.

Hope it will be usefull for others.

Best regards.

Philippe
