I have a customer that has 3 ESXi 5.0 hosts and a vSphere cluster with Standard licensing. These 3 hosts connect to an EMC SAN via iSCSI. I have a new UCS Chassis with 3 blades and a new EMC SAN connecting via Fiber Channel. What is the best way to accomplish a migration to the new cluster with minimal downtime? I just did this recently for a customer (3 new hosts and new SAN but they had enterprise licensing and I didn't build a new vSphere).. That customer also was using iSCSI on both old and new SANs.. I just added an iSCSI connection on each of the 3 new hosts to the iSCSI switch on the old environment and then the 3 new hosts saw both old and new storage.. But again, they had enterprise licensing.. I was planning on adding an iSCSI connection from the new UCS chassis to the iSCSI switch of the "current" SAN but unsure of what route to take after that.. I can build my new vSphere 6 on the new hardware.. I would then get the full functionality for X days.. However, I can't add one of the existing hosts because they wouldn't have storage motion.. I'm sure this has been done many times.. If someone can provide the best route to take on this I'd greatly appreciate it. Thanks

So I have two hosts in the same cluster setup the same exact way.. One host is using both iSCSI vmKernel ports while the other isn't.. Can someone tell me what sets this? Using software iSCSI to an EMC VNX 5300.

I'm running ESXi 4.1. I have, what I believe to be, a disk I/O issue.. I have an EMC AX4-5i with two hosts.. Trying to do a storage vmotion (with the VM powered off) took over an hour before it would actually show the progress of 1%.. I had to cancel it.. Powering on a VM took over 3 minutes to login (and it was a fresh VM from template).. Trying to install Veeam on a VM took over 60 minutes to get past the "analyzing" part.. Today I was copying files from VM to VM and while running esxtop the DAVG/cmd was over 3,000 on one of the hosts.. One of the VMs lived on host A and the other lived on host B.. Host B's esxtop DAVG/cmd didn't go over 100.. One thing to note is that the AX4's write cache is currently disabled because of a bad SPS.. I just don't know if that can cause such severe performance degradation.. Any help would be appreciated. Thanks

I have a ESXi 4.1 installation and I'm trying to add licensing to it. We purchased vSphere 5 licensing because we are going to eventually upgrade. We were under the impression you can apply vSphere 5 licensing to vSphere 4.. Is this not the case? Thanks         

I have a new ESXi 4.1 installation and I'm having constant issues losing connectivity to the hosts when in vSphere client. The host (and all VMs on that host) will show as disconnected randomly for 5-10 seconds.. This happens several times a day.. I also have issues deploying from templates and vmotioning VMs.. I will get a communication error every once in a while.. I click OK on it and try again and it usually works.. I opened a case with VMware but nothing yet.. He thinks it's DNS related, however, everything looks fine on my DNS servers.. Although there is funky results.. For example.. I have 6 BL490c's.. I ssh into one of them and do nslookups on all 6 ESXi hosts by name and by IP.. When I did this last week, it returned the FQDN on 5 out of the 6 hosts.. On one of the hosts, HOST4, it just returned the name, and not the FQDN.. Today, I did the same thing and it again returned 5 out of 6 hosts FQDN.. However, this time, HOST2 was just the name and not the FQDN.. Both DNS servers that my ESXi hosts point to have valid A records and valid reverse lookup records so I have no idea what to look at now.. Any help would be greatly appreciated.. Thanks
