ESXi lost datastore (HP MSA P2000 G3)

[DTLN]

Hello all, I would like to discuss a problem that I encountered.

Configuration:

2x HP Proliant DL360 Gen8 / 112GB RAM / HBA HP H221 (Cluster)

1x HP MSA P2000 G3

ESXi version 5.1 Update2 HP Customized

Vcenter 5.1 Update2 (virtual appliance)

Everything supported firmware / bios versions up to date.

Both servers have 2paths to datastore. Only one LUN is provisioned to esx servers.

After istalling esxi on both servers I have deployed vcenter appliance, builded ha cluster and deployed some VMs everithing works perfectly.

After cca 1 week one server lost both paths to datastore (MSA). After restart host everything works like before few days and problem occures again.

I noticed, that failed host (lost datastore) is allways one on witch vcenter appliance is running. The worst thing is, ha agent not restarts vms on another host untill I physically turn that host off.

Workaround was, I reinstall vcenter on third host that is not part of the cluster, only member of datacenter and has only local storage (not msa).

Are you kidding me vmware ?

Hello, this worked also in a similar scenario where we reconnected second of two hosts (ESXi 6.0 U2, hosts DL360 G9, HBA Sc08 (LSI2008)) and it could not see some of the available LUNs that it saw before and that the other host also was seeing just fine. I followed the suggestion (In vCenter, on the host, configuration, advanced settings, vmfs 3, Set "VMFS3.hardwareacceleratedlocking" to 0.) - the other (working) host had already 0 there. Right click on storage adapter on the list, rescan, boom! - all's available and even datastores.

Thanks a lot!
