What I Am Doing

#EMC cx4 SPA just failed for the 4th time. Still waiting on their devel group for a patch. 51 minutes ago
Updating a UCS blade. Can't wait to totally be at v1.3(1c). Hit a few random bugs in 1.2 1 day ago
#Cisco UCS 6120 Startup Times: http://wp.me/pm3nc-f5 1 day ago
Thankfully this vSphere host is working on the B250 blade. Had to remove/re-add it to the Nexus 1000v though 1 day ago
@zhodd yup. Seems like some sort of pinning is now messed up on that blade 1 day ago
So moved the service profile for vSphere host from a B200 UCS blade to a B250 spare. Hope this fixes it for tonight 1 day ago
@lynxbat ROFL. Nice. 1 day ago
@lynxbat are you sure that you are not some automated bot somewhere in an EMC lab? I swear you don't sleep 1 day ago
Time to migrate it to another blade in UCS 1 day ago
No errors in UCS but VMware still shows 2 nics and 1 FC path down 1 day ago
