Note – 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:
# cfgadm -x remove_device c0::dsk/c0t1d0
Removing SCSI device: /devices/pci@1f,4000/scsi@3/sd@1,0
This operation will suspend activity on SCSI bus: c0
Continue (yes/no)? y
dev = /devices/pci@780/pci@0/pci@9/scsi@0/sd@1,0
cfgadm: Hardware specific failure: failed to suspend:
------------------
/dev/dsk/c0t0d0s0
/dev/dsk/c0t0d0s6
This warning is issued because these commands attempt to quiesce the (SAS)
SCSI bus, but the server firmware prevents it. This warning message can be safely
ignored in the Sun Netra T5440 server, but the following step avoids this warning
message altogether.
3. Remove the hard drive from the device tree.
To remove the hard drive from the device tree, type the following command:
# cfgadm -c unconfigure Ap-Id
For example:
# cfgadm -c unconfigure c0::dsk/c0t3d0
This example removes c0t3d0 from the device tree. The blue OK-to-Remove LED
lights.
