HSG80 Array Controller V8.7 Command Line Interface Reference Guide
2–109
SET controller
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.
IMPORTANT: This value must not be zero (default) in dual-redundant configurations in 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 (1–65535) of idle time on a unit may elapse before
the write-back cache flushes its entire contents to the disks of this idle unit. The
default setting is 10 seconds. When 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 StorageWorks Command Console. When changed, the new
setting for this switch takes effect immediately.
This switch works in SCSI-2 mode only. This switch has no effect in SCSI-3
mode. SCSI mode is set by the SCSI_MODE switch of this command.
•
Select COMMAND_CONSOLE_LUN to enable the CCL.
•
Select NOCOMMAND_CONSOLE_LUN to disable the CCL.
If all LUNs have already been allocated and you attempt to enable the CLL, the
following message displays:
Error 1230: Command console LUN can’t be enabled because all LUNs are
allocated.
CONNECTIONS_LOCKED
CONNECTIONS_UNLOCKED (default)
Controls access to the connection table maintained in NonVolatile RAM
(NVRAM). When the table is locked, the host login request (PLOGI) is rejected
(unless the connection is already in the table) and the request is stored internally in
a rejected hosts table. If a login request is received when the connection table is
unlocked, the connection is granted if there is room in the connection table.
•
Select CLI> SET <THIS | OTHER> CONNECTIONS_LOCKED to lock the
table.
