Releasing An Hdd/Ssd From The System - Oracle Fujitsu SPARC M12-1 Service Manual

5.4.2

Releasing an HDD/SSD From the System

To use the hot plug function, the hotplug service of Oracle Solaris needs to be
enabled. Check the status of the service. If it is disabled, enable the hotplug service in
the following procedure. The hot plug function is available only on the control
domain and root domain.
Note - Unless the system has a redundant configuration, the data on the HDD/SSD will be
lost. Thus, perform this operation only after backing up the data in advance. In addition,
active/hot maintenance of the boot device in a non-redundant configuration cannot be
performed.
# svcs hotplug ← If the STATE is disabled, enable the service.
# svcadm enable hotplug ← Enables the hotplug service.

In HDD expansion, use the cfgadm -a command to check the number of disks
mounted.
# cfgadm -a
