Missing datastores on one reinstalled ESXi 5.5 server from 3-node cluster

[KocoOn]

Hello,

I have 3-node Essentials Plus licensed cluster. vCenter server and all hosts were on 5.1 version. There are about 8 LUNs presented by HP P2000 G3 FC array through FC switches, but no any zones, each server can see all LUNs.

I decided to upgrade the infrastructure to version 5.5, HCL check OK.

vCenter server was upgraded succsfully, it works well. I v-motioned virtual servers to the other two hosts and reinstalled one ESXi server. Upgrade was not possible because of some error stating different broadcom vibs or what... Reinstall was successful, I added this host to vCenter datacenter and to cluster also. I can see devices presented by FC array, but there are no datastores even after rescan HBA and VMFS. ESXi server was installed from HP the latest offline bundle.

Thank you for ideas, if any...

Have you tried checking if the claimrules are different between the legacy 5.1 host and the new 5.5 host by running

storage core claimrule list

against each?

You could also see if

esxcli storage san fc events get

returns any events which point to issues on the 5.5 FC adapter post upgrade.

That's where I would start to look 😉

make zone ， map host and lun

hello

you have a default zone then so indeed all host should see the luns (better to have a zone ofcourse)

what image you used? vmware or vendor customized?

i solved the problem after upgrading to ESX 5.5U1 by logging into my FC switch and configuring the ports again where the server is connected on.

that did the trick for me. after rescan i could see my datastores again

hope this helps you

Thank you for your hints.

I didnt find the command "storage", just "storageRM". And there are no any SAN FC events listed.

On Friday late afternoon I decided to reinstall the host back to 5.1 U1 version (all hosts were installed with HP customised ISO - 3x HP DL380p Gen8) and I disconnected FC connectivity during the installation. The result is the same as with 5.5, but if I rescan for LUNs and datastores, some of them appear for a while, but usually with wrong information about a capacity and free space. The same information is also reported on the other hosts for a few seconds or until "Refresh" is invoked.

And when I list /vmfs/volumes directory, I can see datastores name aliases, but there is some statement with datastores GUIDs:

/vmfs/volumes # ls -alix

ls: ./datastoreGUID: Function not implemented
