Operating syste

m restrictions

The following o

perating system restrictions apply:

• Microsoft Windows operating systems require a unique, dedicated disk for booting. Therefore,

each server connected to a RAID array must have its own disk, or LUN (logical unit number), dedicated solely for booting and operating system ﬁles. Data can be allocated across both the boot disk and the remaining disks. Booting from array-based disk partitions is possible.

NOTE:

The memory paging system requires fast access to the pagefile.sys ﬁle. Insomecases,inSAN environments with heavy I/O loads, the access request for moving information to or from the paging ﬁle may be delayed. This can cause the operating system to halt, requiring a reboot to recover. Microsoft recommends that if paging errors occur, page ﬁles should be relocated to disks that are built into the server using its internal data paths. See the following Microsoft article for additional recommendations related to booting from a SAN:

http://support.microsoft.com/default.aspx?scid=kb;EN-US;q305547.

• For Windows Server 2003, a crash dump ﬁle will not be generated if, at the time of a

system crash, the active path to the system drive is different from the active path established when the system was turned on. To ensure that a crash dump is created, restore the path that was the active path at boot time as soon as possible after the failure, and make it the active path. For detailed information, see the Crash Dump File Creation section in

h Boot%20from%20SAN%20in%20Windows.doc.

• You must use Windows Server 2003 SP1 in a Continuous Access EVA conﬁguration. Boot Vdisks

and application Vdisks must be in separate DR groups. Boot Vdisks for a server or clustered servers must be in a separate DR group.

Clustered server restrictions

This section describes clustered server restrictions for SCSIPORT and Storport miniport drivers.

SCSIPORT miniport driver restrictions

The following SCSIPORT miniport driver restrictions apply:

• Microsoft requires that Microsoft Cluster Servers (MSCS) keep boot disks and shared

storage paths on separate data paths. See the article on the Microsoft web site

http://support.microsoft.com/default.aspx?scid=kb;en-us;305547.

• These conﬁgurations require a minimum of four HBAs.

Storport miniport driver restrictions

The following Storport miniport driver restrictions apply:

• For Storport miniport driver restrictions, see the following Microsoft articles:

• To properly set up MSCS, see "Cluster is formed by using a local quorum resource after a

cluster setup failure in Windows Server 2003," available on

http://support.microsoft.com/kb/912944/en-us.

• For boot from SAN and MSCS conﬁgurations on Windows Server 2003 systems, see "The

updated Storport storage driver, version 5.2.3790.2494, is available for Windows Server 2003," available on value to a Windows Server 2003-based computer that you start from a SAN so that the startup disk, the pageﬁle disks, and the cluster disks that are all on the same SAN fabric," available on

http://support.microsoft.com/kb/886569/en-us.

• To avoid improper modiﬁcation of the registry, use the Boot from SAN Cluster Registry Update

utility to add the ManageDisksOnSystemBuses key. Download the utility (BFSCLRegUp.exe)

from

• A minimum of two HBA ports per host is required for any High Availability (HA) conﬁgurations.

Standalone server restrictions

In a standalone server environment, an HBA port can share boot and data paths.

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 an internal disk for your paging ﬁle system, move this disk to the replacement server. You canalsouseanewdisk,butyoumustformatitandmanuallyresetthepagingtothatdisk.

Prerequisites

The following procedures are not described in detail in this document. However, they must be performed before performing the boot setup procedures.

RAID arrays

Perform the following for EVA, MSA, and XP arrays:

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

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

no zoning conﬂicts.

g HBA zoning to avoid time-out conditions

In boot from S the boot HBA, a time-out condition may occur when the boot HBA interacts with the non-boot HBAs, causing a crashdump to not be generated. To avoid time-out conditions, reconﬁgure the zoning so that the boot instance for each path is in its own zone, separate from the other non-boot HBAs. This may also res
