Sun Microsystems 440 manual Remove the hard drive from the device tree

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:

#cfgadm -x remove_device c0::dsk/c1t1d0

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@1f,4000/scsi@3/sd@1,0

cfgadm: Hardware specific failure: failed to suspend:

Resource		Information
------------------	-------------------------
/dev/dsk/c1t0d0s0	mounted	filesystem "/"
/dev/dsk/c1t0d0s6	mounted	filesystem "/usr"

This warning is issued because these commands attempt to quiesce the Ultra-4 SCSI bus, but the Netra 440 server firmware prevents it. This warning message can be safely ignored in the Netra 440 server, but the following procedure 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 c1::dsk/c1t3d0

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