P2000 G3 SAS and ESXi 5.5 - Unknown WWN

[M. N.]

I connected 2 DL380 G7 running VMware ESXi 5.5 to a P2000 G3 SAS already used by two other DL380 G7 servers running ESXi 5.0.

The P2000 G3 SAS is composed by 2 enclosures and 4 LUNS.

After connecting the cables I found 4 new hosts in the P2000 console:

• 2 hosts whose name is the WWN associated with the vmhba2 adapter of each new host
• 2 hosts whose name is the same as the previous ones with the last number increased by 1

 Is it normal?

I renamed the first two hosts with the names of the ESXi hosts and confngured the host mappings.

What have I to do with the other 2 hosts?

Should I delete them or shoud I confngure them?

Is there any documentation about this configuration procedure?

You will see all hosts wwn that the array discovers. By renaming you set an alias used for mapping. Assuming 4 servers are redundant connected, you will see 8 host entries. Use these hosts for proper mapping. The SMU guide has the details.

Thank you for the quick answer.

If I see only 6 hosts (2 for the existing hosts, 4 for i new ones) does it mean that the old hosts are not configured properly or that the new one are not configured properly?

Where can I locate the SMU guide? I looked for documentation without finding so much about the SAS confnguration...

Let me ask for an additional clarification: if the current confnguration is not optimized, is there any risk to damage the contents of the disks?
