Host Operating System Notes

UNIX Release Notes
Host Operating System Notes
The following section lists host-specific operating notes.
Host Operating System Support of Multi-Bus Failover
Tru64 UNIX V5.1x has multi-bus failover support built into the operating system,
which takes advantage of the array controller’s ability to support multi-bus
failover. Tru64 UNIX V4.0x does not support multi-bus failover.
Booting Tru64 UNIX from the Array
Tru64 UNIX Versions 5.1A and 5.1B support booting the operating system from
the RAID Array.
Command Console LUN
The array controller can provide a dedicated communications LUN called the
CCL. The CCL can simplify the installation and operation of SWCC.
Because the CCL is enabled by default:
■ For Versions 5.1A and 5.1B, when the controller is in SCSI-3 mode, the CCL
is enabled and identifies itself as a controller type. A device special file for
this type (scp) is created in the
/dev/cport directory.
This logical device should be left intact for future installation of SWCC.
TruClusters Controller Devices as Member Boot Disks
Alpha System Reference Manual (SRM) console firmware V6.7 or later must be
installed on any cluster member that boots from a disk behind an array controller.
If the cluster member is using V5.6 firmware or earlier, the member may fail to
boot, indicating “Reservation Conflict” errors.
The latest Alpha SRM console firmware can be obtained from the following web
site:
