Note that while you can use the Solaris OS cfgadm install_device and cfgadm
remove_device commands to perform a hard drive hot-plug procedure, these
commands issue the following warning message when you invoke them on a bus
containing the system disk:
This warning is issued because these commands attempt to quiesce the (SAS) SCSI

For example:
This example removes c1t3d0 from the device tree. The blue OK-to-Remove LED

# cfgadm -x remove_device c1::dsk/c1t3d0
Removing SCSI device: /devices/pci@0/pci@0/pci@2/scsi@0/sd@3,0
This operation will suspend activity on SCSI bus: c1
Continue (yes/no)? yes
cfgadm: Hardware specific failure: failed to suspend:
