5.4.2 Releasing an internal disk 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 internal disk 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. |
For details on the cfgadm command used here, see "2 Dynamically Configuring Devices" in the Managing Devices in Oracle Solaris 11.2 or "Dynamically Configuring Devices (Tasks)" in the Oracle Solaris Administration: Devices and File Systems.
- Execute the cfgadm command to check the configuration of the internal disk.
If you replace or reduce an internal disk, use the cfgadm -a command to check the Ap_ID of the disk requiring maintenance and make a note of it. The Ap_ID refers to a string such as "c4::dsk/c4t5000039428298FFEd0".
If you expand an internal disk, use the cfgadm -a command to check the number of disks mounted.
# cfgadm -a |
- Stop all applications from using the internal disk.
- Execute the cfgadm command to release the internal disk requiring maintenance from the system.
Enter the Ap_ID you noted in advance.
# cfgadm -c unconfigure Ap_ID |
- Execute the cfgadm command to confirm that the internal disk requiring maintenance is disconnected.
The disconnected internal disk is displayed as "unconfigured."
# cfgadm -a |
- Execute the cfgadm command to blink the CHECK LED of the internal disk requiring maintenance, and determine its location.
Enter the Ap_ID you noted in advance.
# cfgadm -x led=fault,mode=blink Ap_ID |
- Check the following LEDs to determine whether the internal disk requiring maintenance can be removed:- READY LED (green) of the internal disk: On- CHECK LED (amber) of the internal disk: Blinking
