Note that while you can use the Solaris OS cfgadm install_device and cfgadm
remove_device commands to perform a hard drive hot-swap procedure, these
commands issue the following warning message when you invoke these commands
on a bus containing the system disk:
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 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:
For example:
This example removes c0t3d0 from the device tree. The blue OK-to-Remove LED
lights.
# 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:
