Environment: vSphere v5
SAN: Dell Equalogics
Issue: had 15 volumes that were able to be seen from vmware. after patching only 10 show up, and ESX gives error: target returned login error of: 0101 for iSCSI
All was working prior to patch. Each is multi-pathed
In Static discovery it looks like the volumes are mapped in the SW iscsi adapter, but in storage 5 of the volumes dont show up
Found this article, but I dont think CHAP is being used.
