Microsoft Cluster Service/Microsoft Failover Cluster

Microsoft Cluster Service (MSCS)/Microsoft Failover Cluster (MSFC) can build
Windows Cluster System by using physical servers.
Note for HBA EFI Driver configuration
Basic configuration items of HBA EFI Driver (Select Boot Device Enable, Boot
Device List) have to be configured on the MSCS/MSFC environment. If the
Basic configuration items of Standby Windows servers are not configured,
data access conflict will occur between Active servers and Standby servers.

Basic configuration has to be configured for Active servers and Standby
servers.
Boot Firmware and Windows Loader starts for starting Windows when boot-up
an LPAR.
The LPAR correctly accesses a target Logical Unit (LU) by using configured
path when the Basic configuration items are configured. However the LPAR
would access all accessible LUs when the Basic configuration items are not
configured.
When a bandwidth of the path to an LU by a standby server is busy, an OS
installed on the LU does not boot or the OS runs slowly.

If a server blade with VMware ESX 4.0 or later is switched to the
standby server blade, BIOS time is changed to UTC by NTP servers.
Then, set the local time to BIOS time of the standby server blade after
recovery.
[When changing server blades]
When VMware ESX 4.0 or later is running, check that BIOS time is set
to UTC in the new server blade. When OS on Basic or that on a virtual
platform other than VMware ESX 4.0 is running, check that BIOS time
is set to the local time in the new server blade.
