To clean up the operating system device tree after removing LUNs

1. Run the format command. In the command output, a device that has been removed includes the text <drive not available>.

   413. c3t5006048ACAFE4A7Cd252 <drive not available>
   /pci@1d,700000/SUNW,qlc@1,1/fp@0,0/ssd@w5006048acafe4a7c,fc

2. Use Storage Array Management or the command line to unmap the LUNs. After they are unmapped, Solaris indicates the devices are either unusable or failing.

   # cfgadm -al -o show_SCSI_LUN | grep -i unusable
   c2::5006048acafe4a73,256 disk connected configured unusable
   c3::5006048acafe4a7c,255 disk connected configured unusable
   # cfgadm -al -o show_SCSI_LUN | grep -i failing
   c2::5006048acafe4a73,71 disk connected configured failing
   c3::5006048acafe4a7c,252 disk connected configured failing

3. If the output indicates the LUNs are failing, you must force an LIP on the HBA.

   # luxadm -e forcelip /devices/pci@1d,700000/SUNW,qlc@1,1/fp
   @0,0:devctl

   This operation probes the targets again, so that output indicates the devices are unusable. To remove a device from the operating system device tree, it must be unusable.

4. Remove the device from the cfgadm database. On the HBA, enter the following commands:

   # cfgadm -c unconfigure -o unusable_SCSI_LUN c2::5006048acafe4a73
   # cfgadm -c unconfigure -o unusable_SCSI_LUN c3::5006048acafe4a7c

5. To verify that the LUNs have been removed, repeat step 2.
6. Clean up the device tree. The following command removes the /dev/dsk links to /devices.

   # devfsadm -Cv
