HP StorageWorks Booting Windows Server 2003 for Itanium-based Systems from a Storage Area Network Application Notes

Server replacement in the event of a server failure

You must retain

the

HBAs to ensure that the replacement server hardware components are identical to the

ones you are replacing. Place each HBA in the PCI slots of the new server in the same order as they

were placed in the old server.

If you are using

internal disk for your paging ﬁle system, move this d isk to the replacement server. You

can

also use a ne

disk, but you must format it and manually reset the paging to that d isk.

Prerequisites

The following procedures are not described in detail in this document. However, they must be performed

before performing the boot setup procedures.

Switch-based zoning,page 6

RAID arrays

Perform the f

ollowing forEVA,MSA,and XP arrays:

• Verify that all existing storage units (virtual disks) have the proper access settings.

• With switch-based con ﬁg urations, if zoning is enabled, check the switch to ensure there are

no zoning conﬂicts.

Working with boot disk partitions

Before creating a boot disk, you must start with a clean, unpartitioned virtual disk. Perform the following

procedures:

• Create a LUN that is at least 32 GB.

• If you plan to set up booting from a RAID array that has other virtual disks attached to other

servers, be aware that when you are setting up booting for the n ew server, the installation

program displays a list of partitions available for loading the operating system. The display

contains a disk for every controller port accessible by the HBA. Althou gh it may appear that there

is more than one virtual disk available for booting, there is only one virtual disk available.
