Hi,
I have a problem with upgrade from 4.1 and also with clean installation vsphere 5 (vsphere hypervisors) on two IBM bladecenter HS22.
They were running about half year on version 4.1 without problems, and now customer want to upgrade to version 5.
The problem is, after some time or on some load storage DS3512 and datastores on them are disconnected from hypervisor. VMs looks like they are runing and response to ping, but nobody can access them, hence HA don't move them on second HS22.
After hard reset of HS22 everything goes well to another "hang". HS22 is responsing normally. In log that hanged HS22 are logged problems with LSI mpt driver and losted connection to DS3512. There is LSI1064e adapter.
I don't know what can I do with that. Both bladecenter servers behave same, after some time they disconnect.
IBM HS22 is on HCL with vspere version 5, HS22's and chassis are on newest firmware.
