New virtual Disk Geometry does not match old geometry (Doc ID 1964565.1)

Last updated on SEPTEMBER 26, 2023

Applies to:

Solaris Operating System - Version 11.1 and later
Information in this document applies to any platform.


Disk geometry problem

Currently we have storage directly provided to our machine from an EMC array
We are currently migrating to storage provided via a VPLEX device (same EMC array backend)

New LUNS have been provided (same number of blocks) but Solaris is identifying the storage with different geometry.
Consequently there is not the same number of blocks available.
Consequently we are unable to mirror our zpools.

Old storage vtoc

This problem is caused by the different geometry causing the 2 spare cylinders to use more blocks in the new storage (more blocks per cylinder)
