Dear Community,
this problem is driving crazy...
We have a cluster of 4 ESXi 5.1 Hosts managed with vCenter 5.1, all latest patch level.
Connected to the Hosts are via Software iSCSI our Active/Passive iSCSI cluster, which is working just fine, and two small iSCSI NAS Systems for minor stuff like Install Images, some backups and so on.
Now, all hosts are configured the same, using profiles, all can without problem access the SAN and the first NAS, but not the second.
These are the steps I took for the first AND the second NAS:
- create RAID5
- create LUNs
- set a iSCSI user and password
- check if the network connection is valid (it is, for both NAS!)
- configure the "Send target" on the ESXi Hosts
- Check that the targets are showing up (they are, 3 for each NAS, making 6 of them!)
- Then add the storage, chosing the filesystem and so on.
And here is where NAS 1 shows up and I can add all the LUNs, format them to VMFS and use them on all hosts, whereas NAS 2 LUNs don't show up.
The NAS systems are configured exactly the same, same hardware, same firmware, they only differ by IP, username and password.
In the NAS 2 system when I click on the LUN it says that the ESXi-Hosts are connected and the LUN connection is active, just like in NAS 1.
So, where could be the problem?
Any hints are highly apreciated ;-)
Best regards,
Thomas
