I'm not sure if this is relevant but I ran into a  similar error today configuring a PS6000 SAN.  After much stuffing around I found that the IP address I tried to configure for the Group IP Address, when pinged, returned a "Destination host unreachable" response as opposed to what you would expect in the form of: "Request Timed Out".  When I tested from other servers I got "Request Timed Out" notifications so I went back to the original server and cleared the routing table by going to the command line and executing a " route -f " with the route utility.  After which pings returned "Request timed out" messages and I could move on through the SAN configuration. Not sure if this will help but I thought I would post in case I can spare someone else the time and hassle.
Hi everyone, we're some problems doing the basic configuration of a PS6000. Getting very frustrated! We have a completely isolated, standalone network set up which consists of two stacked Dell 6224 switches. On the network we have a Windows Server 2008 R2 machine running the Remost Setup Wizard. The server is a basic build, no additonal roles or features added. There is no uplink from the network to any other FW's or networks, it is completely isolated. We have installed the tools that came with the array, and accepted all the necessary changes to the Server's FW, added all the additional components as requitred and so on. We have connected the PS6000 to the network and are running the Remote Setup Wizard to configure it. The first screen detects the PS6000 correctly via its MAC address, we select it and move to the next screen. We assign it a name, an IP address from the subnet range on this network, an appropriate subnet mask and the default gateway. That all goes fine. On the next screen we assign the Group name, Group IP address and all the various Group, joining and CHAP passwords. All the passwords are accepted and approved. However on clicking "Next" we get an error that says: "Incomplete Information - Enter the Following: Group IP (address provided already in use by another host)" and we can't progress any further.  This cannot be the case - the IP address is not in use as there are only 3 other devices on this entire network. There is no DHCP or anything else providing addresses and no other hosts to pick them up. We can put any address we like into this field (within the appropriate subnet, of course) and get the same error message. Pick any random address, it's already in use, or so the Wizard claims. This unit is straight out of the box, never switched on before, never previously configured, brand spanking new. Anyone else experienced this or have any advice? TIA, Tim Lovegrove
