SET SLIDRIVS(,,,,,BD4,BD3,BD2,BD1,BD0),FORLSMID(lsm­id),

FORPANEL(panel)

FORLSMID

specifies that the operation is being restricted to a specific LSM.

(lsm-id)

specifies the LSMid containing the drive panel whose addresses are being changed. An LSMid is made up of the ACSid (hexadecimal 00-FF) and the LSM number (hexadecimal 00-17) separated by a colon (:).

FORPANEL

specifies that the operation is being restricted to a specific panel.

(panel)

specifies the 2-digit ID of the panel containing the drives whose addresses are being changed.

Note: The specified panel must be an existing drive panel in the LSM.

FORHOST

specifies that the operation is being restricted to a specific host. Only the specified hosts’ drive device numbers are set. If omitted, the device numbers for all hosts are changed.

Note: The number of drive positions for a specific host must equal the number of drive positions defined globally (issuing SET SLIDRIVS without the FORHOST parameter).

(host-id)

specifies the 1- to 8-character host ID of the host, to which the operation is restricted.

Running SET SLIDRIVS With the HSC Active

Ideally, the HSC should be shut down on all hosts when you specify this parameter. In some cases, however, the HSC can be left active without causing adverse results. Table 17 defines options for running SET SLIDRIVS.

Table 17. HSC State/SET SLIDRIVS Operation

HSC State	Effect on SET SLIDRIVS
Down	If the HSC is down on all hosts, the HSC recognizes all new drive
	locations when it is initialized. Shutting the HSC down ensures
	that accurate drive information is written to the CDS.
Active	The HSC can be up on all hosts only if new drives are being added
	at new drive locations. The HSC recognizes the new drive
	locations when it is recycled on a host.
