CLI Commands B–29
bus, you can use this switch to restrict hosts from accessing certain
units. This switch limits visibility of specific units from certain hosts.
For example, if two hosts are on the same bus, you can restrict each
host to access only specific units.
If you enable another host ID(s), previously enabled host(s) are not
disabled. The new ID(s) are added. If you wish to enable only certain
ID(s), disable all access paths (DISABLE_ACCESS_PATH=ALL),
then enable the desired ID(s). The system will display the following
message:
Warning 1000: Access IDs in addition to the one(s) specified
are still enabled. If you wish to enable ONLY the id(s)
listed, disable all access paths (DISABLE_ACCESS_PATH=ALL),
then enable the ones previously listed.
Note To enable access by more than one host connection, list the
connection names separated by commas and enclosed in parenthesis.
Enabling access by more than one host connection can also be done by
sequential commands.
PARTITION=partition-number
Identifies the unit number for a partition on a container. The partition-
number identifies the partition associated with the unit number being
added. Use the SHOW container-name command to find the partition
numbers used by a storageset or a single-disk unit.
Note Do not split partitioned units across ports. The subsystem assigns
units 0-99 to Port 1; units 100-199 are assigned to Port 2. Partitioned
units must be on a single port.
Transportable units cannot be partitioned.
MAXIMUM_CACHED_TRANSFER=32 (Default)
MAXIMUM_CACHED_TRANSFER=n
Sets the largest number of write blocks to be cached by the controller.
The controller will not cache any transfers over the specified size.
Accepted write block sizes are 1 through 1024.
