[oi-dev] Illumos/Solaris zpool and GPT Partitions/Slices

[Atiq Rahman]

Hi John,
Are you using a GPT partition table? Also, are you on x86 or SPARC?

I just noticed this on Solaris documentation:
- https://docs.oracle.com/cd/E26502_01/html/E28980/partsys.html (backup
link: https://docs.oracle.com/cd/E37838_01/html/E69250/app-panels.html )

which say,
> If the disk contains existing GPT partitions, the GPT partitions are
displayed. Up to seven GPT partitions are supported. You can create one or
more Solaris partitions during the installation, but you must choose one
Solaris partition as the installation target. If there are multiple,
existing Solaris GPT partitions, the first suitable Solaris GPT partition
will be chosen by default as the installation target.


Best!

Atiq
