Installation Overview
configuration is unsupported. HCL certification requires a separate
private network adapter.
Disks can be shared by the nodes. The requirements for sharing disks
are as follows:
Physically attach all shared disks, including the quorum disk, to the
shared bus.
Make sure that all disks attached to the shared bus are seen from
all nodes. You can check this at the setup level in <Ctrl> <M> (the
BIOS configuration utility.) See
page
7-27, for installation information.
Assign unique SCSI identification numbers to the SCSI devices and
terminate the devices properly. Refer to the storage enclosure
manual for information about installing and terminating SCSI devices.
Configure all shared disks as basic (not dynamic).
Format all partitions on the disks as NTFS.
It is best to use fault-tolerant RAID configurations for all disks. This
includes RAID levels 1, 5, 10, or 50.
During installation, some nodes are shut down, and other nodes are
rebooted. This is necessary to ensure uncorrupted data on disks
attached to the shared storage bus. Data corruption can occur when
multiple nodes try to write simultaneously to the same disk, if that disk
is not yet protected by the cluster software.
