32 SPARC Enterprise T5140 and T5240 Servers Administration Guide • July 2009
Note – The logical device names might appear differently on your system,
depending on the number and type of add-on disk controllers installed.
The –al options return the status of all SCSI devices, including buses and USB
devices. In this example, no USB devices are connected to the system.
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
bus, but the server firmware prevents it. This warning message can be safely
ignored in the SPARC Enterprise T5140 or T5240 server, but the following step
avoids this warning message altogether.
3. Remove the hard drive from the device tree.
Type the following command:
For example:
This example removes c1t3d0 from the device tree. The blue OK-to-Remove LED
lights.
# 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:
