How to Identify LUN Details on Solaris Host for Decommissioning from NetApp Storage
Applies to
- NetApp ONTAP 9.16.1P1 and later
- All NetApp FAS/AFF/ASA storage systems
- Solaris
Answer
Steps to be referred:
- On the Solaris host end, identify the LUN using: WWN / NAA ID (e.g.,
naa.600a098038303456765d4f6c6e2d6xxx) - Use the LUN WWN or Serial Number to find the corresponding LUN on the NetApp, using command
#lun show -fields serial,uuid - Validate Host Mappings and Check which hosts the LUN is presented to using lun mapping show
Additional Information
- If the NAA ID/WWN is not directly available, use host utilities or multipath tools (e.g., luxadm, format, or mpathadm on Solaris) to list all disk devices and their identifiers.
- Match these against the LUN serial numbers or WWNs shown in ONTAP using lun show or lun mapping show commands.
- Always use the unique WWN/NAA ID from the host to validate and identify LUNs on the storage system before decommissioning. This ensures the correct LUN is targeted and avoids accidental removal of the wrong storage resource.
