Table 17. HSC State/SET SLIDRIVS Operation

HSC State	Effect on SET SLIDRIVS
Active	If unit addresses are changed or deleted for an existing drive
	location, either
	• the affected LSM must be offline until the HSC has been
	recycled on all hosts, or
	• the affected ACS must be offline to all affected hosts that access
	an HSC that has not been recycled.

SET SLIDRIVS Procedure

The following procedure shows one method for changing unit addresses with the HSC active.

•For one host:

1.Modify the affected LSM offline (MODify lsm-id OFFline). The LSM will be offline to all hosts.

2.Use SET SLIDRIVS to update the CDS drive records while the StorageTek CSE(s) is making the hardware changes.

3.Recycle the HSC on one host.

4.Vary the affected ACS offline (Vary ACS(acs-id) OFFline) on all hosts running an HSC that has not been recycled.

5.Modify the affected LSM online (MODify lsm-id ONline). The LSM will be online to all hosts where the ACS is online.

Note: Only hosts that are online to the ACS and that are running a recycled HSC will mount to drives connected to this LSM.

•For the remaining hosts, recycle the HSC, and the affected ACS will come up.

SET LMU Station Address Numbers

SLISTATN

specifies that the LMU station addresses are to be set. The change does not take effect until the affected HSC(s) is recycled. An affected HSC is one that resides in the host specified in FORHOST. If FORHOST is omitted, all HSCs are relevant because the operation is not restricted to a specific host.

(stat1,...,stat16)

specifies the LMU station addresses associated with a particular ACS. No station addresses are required. Up to 16 can be specified, separated by commas

Notes:

1.When adding one or more station addresses to an existing list of stations, you must specify all old stations as well as new ones. Any stations (for this
