[. . . ] However, a reduced RAIDset does not make the concatset inoperative. The maximum total disks in a concatset is 24. Storagesets must have been initialized before being added to the concatset. The CLONE utility cannot be used on a concatset. Concatsets cannot be used in remote copy sets. · · · · · · · Syntax SET concatset-name Parameters concatset-name The name of the concatset to be expanded. Switches ADD=storage-set-name 2­102 HSG80 Array Controller V8. 7 Command Line Interface Reference Guide SET concatset-name Concatenates the storageset specified by storage-set-name to the concatset. Examples To expand the capacity of unit D0 which consists of stripeset Stripe1, by adding another stripeset (Stripe2), enter: ADD CONCATSETS C1 STRIPE1 SET C1 ADD=STRIPE2 See Also ADD CONCATSETS DELETE concatsets SHOW CONCATSETS HSG80 Array Controller V8. 7 Command Line Interface Reference Guide 2­103 CLI Command Descriptions SET connection-name Changes the operating characteristics of a host connection. Each path between a Fibre Channel adapter in a host computer and an active host port on a controller is a connection. This command adds the specified host connection to the table of known connections. This table is maintained in the controller's memory. The maximum table length is 96 connections; if the table contains 96 entries, new connections cannot be added unless some old ones are deleted. The SET connection-name command changes the operating parameters of the specified host connection. A host connection is a specific instance of one host connected to one port of one controller through one host adapter. Syntax SET connection-name Parameters connection-name This is the name of the host connection. When a new host-adapter-port-controller connection is made, the new connection is given a default connection name. The default connection name is !NEWCONnn, where nn is a decimal number. The connection name can be changed through the RENAME command. Switches The following switches are available for the SET connection-name command: · · · OPERATING_SYSTEM RESERVATION_STYLE UNIT_OFFSET These switches are described in the following paragraphs: 2­104 HSG80 Array Controller V8. 7 Command Line Interface Reference Guide SET connection-name OPERATING_SYSTEM=OS_name Specifies the operating system of the host. The OPERATING_SYSTEM switch tailors the controller's behavior for use with a particular operating system. See your operating system specific Solution Kit to determine which value should be used. The following values are supported: WINNT, TRU64_UNIX, VMS, HP, HP_VSA, IBM, NETWARE, SGI, SNI, SUN, AIX_CAMBEX. RESERVATION_STYLE=CONNECTION_BASED (default) RESERVATION_STYLE=HBA_PORT_ID_BASED Selection of a RESERVATION_STYLE should be based upon the capabilities of the host operating system. [. . . ] A utility that allows viewing of specific informational displays using CLI commands. wide Ultra SCSI Fast-20 on a Wide SCSI bus. HSG80 Array Controller V8. 7 Command Line Interface Reference Guide Glossary­27 Glossary worldwide name A unique 64-bit number assigned to a subsystem by the Institute of Electrical and Electronics Engineers (IEEE) and set by DIGITAL manufacturing prior to shipping. Also called node ID within the CLI. write hole The period of time in a RAID level 1 or RAID level 5 write operation when an opportunity emerges for undetectable RAIDset data corruption. Write holes occur under conditions such as power outages, where the writing of multiple members can be abruptly interrupted. A battery backed-up cache design eliminates the write hole because data is preserved in cache and unsuccessful write operations can be retried. write-back caching A cache management method used to decrease the subsystem's response time to write requests by allowing the controller to declare the write operation "complete" as soon as the data reaches its cache memory.
