LUN Disapears

Morning All,

we have an ESX server connected to a ISCSI LUN on DSS.

everything had been working great until last night, all of a sudden the virutal machine hosted on the LUN just froze, after a lot of std troubleshooting we checked the Storage adapter (within ESX) and the lun wasn't there

checked the connections on the DSS and its showing an inbound connection the ID is that of the ESX ISCSI but the ip is listed as 192.168.0.221 (not 220 which the IP of the box)

I have tried allsorts to try and get the connection back but it appear that no matter what connects to the DSS no drive is ever presented (tried with microsoft ISCSI connector but nothing show'd up under disks)

can anyone help ??

we may have some movement, but how can you resize a lun downwards ???

it might be that ESX doesn't support LUNS over 2Tb

we orginally had one that was 1 but we extended it to 2.5Tb, within the lun the VMFS is only 1Tb so, how do i resize the partition down ???

this might not be the way forwards but we need that data so any help would be great

Below is the link for ESX 3.5 maximum configurations - looks as though they do not support over 2TB in size. Also we do not have a function to decreases the size of the logical Volumes only to increase them. I was thinking of replicating the your Target to another system with our Demo-CD but not sure if you would have to initialize the Target then disable the Target then replicate from the Source (being the different volumes size), once complete enable the Destination as Source and enable the Target. But never done this before.
