Solaris LUN increase

chinchillaking — Wed, 04 Jun 2025 10:52:48 GMT

Hi,

We check NetApp KB refer "Solaris LUNs cannot be resized due to their partitioning scheme" as below.

https://kb.netapp.com/?title=Advice_and_Troubleshooting%2FData_Storage_Systems%2FFAS_Systems%2FUnable_to_increase_the_lun_size%253B_lun_reached_maximum_resize_value

But some of Solaris version support "zpool autoexpand", could NetApp support LUNs increase if use Solaris zpool?

Best regards

I am not an ONTAP expert, but after reading Support Bulletin SU34, I do not think it would be a good idea to try to force the expansion with "zpool autoexpand".

At this time, it looks like expanding the ONTAP-hosted Solaris volume from either side is not supported.

Resizing a LUN with the OS type as 'solaris' is deprecated beginning with ONTAP 9.0

If you are i need of resizing the LUN, a workaround may apply. you can open a case and mention the following KB: LUN resize function not implemented for Solaris LUN

Hi,

If NetApp LUN present to Solaris not support resize due to Solaris partition scheme issue, how about LUN present to Solaris host but use Veritas vxvm vxfs or Oracle ASM? Is resize LUN OK?

Hello @chinchillaking,

LUN resize is Supported with both Veritas VxVM and Oracle ASM, reference document page TR-3633: Oracle Databases on ONTAP.
