Creating system packages with UCS-specific settings
To provision the operating system on a bare-metal blade, you create a system package for the operating system that you want to provision on the blade. Depending on the operating system and chipset combination that you are provisioning, you might need to include UCS-specific configuration settings in the system package. For more general information about creating a system package, see System package panels (generic).
The following table presents special guidelines for UCS-specific configuration that you must perform, depending on the specific operating system for which you are creating the system package:
|Operating system||System package panel or tab||Configuration guidelines|
|Windows (all versions)||Disk partition - Windows|
|Post-disk partition - Windows|
Include the following lines:
|Windows 2003||Computer settings - Windows|
|Windows 2008||Unattend Entries - Windows 2008|
|Red Hat Enterprise Linux||Basic configuration - Red Hat Linux|
The Intel NIC (Intel 82598EB 10 Gigabit AF Dual Port Network Connection) available with UCS hardware requires the IXGBE driver. This driver is available by default with Redhat 5.3. However, IXGBE has a defect that can cause provisioning to fail, and Red Hat recommends a workaround.
By default, the IXGBE driver compiles with the LRO (Large Receive Offload) feature enabled. This option offers the lowest CPU utilization for receives, but is completely incompatible with routing/IP forwarding and bridging. If enabling IP forwarding or bridging is a requirement, you must disable LRO using compile time options. If you do not disable LRO and then enable IP forwarding or bridging, you may experience low throughput or even a kernel PANIC.
As the first step in the IXGBE workaround:
|Kickstart entries - Red Hat Linux|
|Disk partition - Red Hat Linux||For SAN provisioning, in the Disk Drive field specify to which disk the actual SAN disk is mapped. The SAN disk might be mapped to |
|ESX 3.5||Disk partition - ESX|
For SAN provisioning, in the Disk Drive field specify to which disk the actual SAN disk is mapped. The SAN disk might be mapped to
