9.3 Releasing I/O Resources From a Logical Domain


9.3 Releasing I/O Resources From a Logical Domain
Depending on the FRU requiring maintenance and the system configuration, active maintenance is possible in some cases, but it might be necessary to restart or stop Oracle Solaris.
This section describes the procedure for releasing the I/O resources listed below from Oracle Solaris on a logical domain before FRU maintenance on the SPARC M12. Table 9-1 lists the types of I/O resources to be released and their references in this section.
For details on the commands used here, see "3.2 Operations and Commands Related to Logical Domain Configurations" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide and the manual for the software being used.
If the hotplug service of Oracle Solaris is disabled, enable it by following the procedure below, and then release the I/O resources.
  1. Check the status of the hotplug service.
# svcs svc:/system/hotplug:default
STATE STIME FMRI
disable 16:26:10 svc:/system/hotplug:default
  1. Enable the hotplug service.
# svcadm enable svc:/system/hotplug:default
  1. Confirm that the hotplug service is enabled.
# svcs svc:/system/hotplug:default
STATE STIME FMRI
online 16:26:10 svc:/system/hotplug:default
Note - To perform active maintenance on a FANU, a PSU, or the XSCF unit, the work described in this section is not required.
