Command Line Interface Reference Guide
Caution: If the storage subsystem has more than one host connection, the
access path must be specified carefully to avoid giving undesirable host
connections access to the unit. The default condition is that access paths to all
host connections are enabled. To restrict host access to a set of host
connections, specify DISABLE_ACCESS_PATH=ALL
if the unit is added,
then use the SET unit-number command to specify the set of host
connections that are to have access to the unit.
Enabling the access path to a particular host connection does not override
previously enabled access paths. All access paths previously enabled are still
valid. The new host connection is added to the list of connections that can
access the unit.
The procedure of restricting access by enabling all access paths and then
disabling selected paths is
not recommended because of the potential data or
security breach that occurs if a new host connection is added.
MAX_READ_CACHED_TRANSFER_SIZE=n
MAX_READ_CACHED_TRANSFER_SIZE=32 (default)
Sets the largest number of read blocks to be cached by the controller. The
controller does not cache any transfers over the size set. Acceptable values are
0 through 2,048.
The MAXIMUM_CACHED_TRANSFER switch affects both read and writeback
cache if it is set on a controller that has read and writeback caching.
MAX_WRITE_CACHED_TRANSFE_SIZE=n
MAX_WRITE_CACHED_TRANSFER_SIZE=32 (default)
Sets the largest number of write blocks to be cached by the controller. The
controller does not cache any transfers over the size set. Acceptable write
block sizes are 0 through 2,048.
The MAXIMUM_CACHED_TRANSFER switch affects both read and writeback
cache after set on a controller that has read and writeback caching.
MAXIMUM_CACHED_TRANSFER_SIZE=n
MAXIMUM_CACHED_TRANSFER_SIZE=32
(default)
Sets the largest number of read and write blocks to be cached by the
controller. The controller does not cache any transfers over the size set.
Acceptable block sizes are 0 through 2,048.
