Inaccessible Datastore..

Hi, all.

I have some problem with datastore.

ESXi hosts were rebooted cause by power outage.

After reboot, 2 of many datastores shown 'inaccessible'.

I tried reboot all esxi hosts, rescan vmfs, but it doesn't resolved.

vmfs volumes are connect with host because I can verify inaccessible status vmfs volumes in esxi host using 'esxcli storage core device list'.

When I re-mount or delete datastore, I encountered 'An error occured during host configuration'.

That error message don't give me no more information.

When I check the vmkernel.log, the log below is printed.

I did googling with this log, but I couldn't find any information.

What more can I check? Should I check this on the storage side?

Regards.

Hi

Please share more information such as your storage configuration, local or shared datastores and etc.

There are lots of reasons that may cause this problem, but one of the main reasons for "inaccessible datastore" is related to your storage controllers. first of all, please check that you don't have any problems on the storage side. for example check for some connection lost or SCSI endpoints configuration and etc.

If there are some dedicated datastores for that specific host that are now lost, you should check your server "storage controller" hardware and software status (firmware and driver)

I hope this could be helpful

That is shared datastores.

Finally, I opened case.

Thank you for your reply !
