ScsiPath: 5560: Plugin 'NMP' had an error (Failure) while claiming path

[AHuntington]

Hey Guys,

Got these logs on all 3 of my ESXi hosts, but can;t find much on it, any ideas?

ESX03:

Any help would be greatly appreciated!

I think the warning is against a VVOL device, have you configured VVOL storage on these hosts?

Let me know what is the version of ESXi (version & build#) and storage array/device details.

[AHuntington]

Hi rpetchim,

Cheers for the reply!

No not running VVOL on any of the hosts.

Current build ESXi 6.0.0, 2494585

Storage: EMC VNXe 3200 (3.1.1.6207002)

- iSCSI 10GbE

- 2x 2.1TB VMware Datastores

All the storage for VMware is managed from Unsphere intergration with vCenter.

Hope that covers it all?

[rpetchim]

Sorry for late reply.  Is the concern only with these warning messages or is there other issue (device missing or unable to connect/showup)?

It is not clear to me why a VVOL warning message seen here when there is no VVOL configuration.

if the concern only with these warning messages then you can disable VVOL by executing below command:

# esxcfg-advcfg  -g /Scsi/ScsiEnableVVOL

Value of ScsiEnableVVOL is 1

# esxcfg-advcfg  -s 0 /Scsi/ScsiEnableVVOL

Value of ScsiEnableVVOL is 0

Thanks.

No worries mate, thanks for the help.

I'll give that a crack and see how it goes!

Finally got a an outage window, migrated all the VM's off and made the required changes. After migrating them back so issues i can see but still getting errors int he event log. Odd as thee seems to be no impact on any of the VMs.
