PURE FlashArray Phantom LUN 0 is not Enumerated in Solaris (Doc ID 2997457.1)

Last updated on JANUARY 11, 2024

Applies to:

Solaris Operating System - Version 11.4 and later
Information in this document applies to any platform.


Logical Unit Number(LUN) 0, a SCSI Requirement(Doc ID 1017707.1)

"All SCSI devices shall accept LUN 0 as a valid address. For SCSI devices that support the hierarchical addressing
model the LUN 0 shall be the logical unit that an application client addresses to determine information about the
SCSI target device and the logical units contained within the SCSI target device."


There is a common misunderstanding that LUN 0, which is a SCSI requirement, cannot be configured in Pure Flasharray Storage.
Unlike EMC which simulates LUN 0 (if not created) by creating a LUNZ, Pure FlashArray has a phantom LUN 0 which is hidden (i.e, not enumerated) from Solaris.

This document will show examples on how to check the output of fcptrace when LUN 0 exists and a certain  condition when it does not exist
