ALLOCATION_CLASS
Allocation class is a unique identification number assigned to the controller
pair under certain operating systems. The value for an allocation class is
0-4,294,967,295; for Tru64 UNIX®, it is a 4-byte number. It is reported in
response to the SCSI inquiry command and is the same for all units connected
to one or both controllers. The allocation class value allows the host to
identify the controllers that are a matched dual-redundant pair. This number
should be unique for every pair of dual-redundant controllers in the cluster.
Note: This value must not be zero (default) in dual-redundant configurations for host
systems that implement allocation class. A zero value in this configuration causes the
operating system to disable failover between the controller pair. Some operating
systems do not implement allocation class, in which case the default of zero has no
meaning.
CACHE_FLUSH_TIMER=n
CACHE_FLUSH_TIMER=10
(default)
Specifies how many seconds (1–65,535) of idle time elapses on a unit before
the writeback cache flushes its entire contents to the disks of this idle unit.
The default setting is 10 seconds. If changed, the new value entered for this
switch takes effect immediately.
COMMAND_CONSOLE_LUN
NOCOMMAND_CONSOLE_LUN
Enables or disables the command console LUN (CCL), a communication
LUN used to initially setup SWCC. If changed, the new setting for this switch
takes effect immediately.
TERMINAL_SPEED
4,800, 9,600 (default) , or 19,200
TIME Two-digit day, three-character month,
four-digit year, and two-digit hour,
minute, and second
UPS=NODE_ONLY
UPS=DATACENTER_WIDE
NOUPS
