How to Verify a Lun is in Active/Optimized Mode when ALUA Is Configured on Storage (Doc ID 2533184.1)

Last updated on MAY 26, 2021

Applies to:

Oracle VM - Version 3.4.5 and later
Linux OS - Version Oracle Linux 6.0 and later
Linux x86-64

Goal

If the Linux server has device-mapper-multipath configured, you can run 'multipath -ll' to list how disks are grouped together. For ALUA mode, you can check if a disk is in the Acitve/Optimized or non-optimized group.

This note, however, is to discuss how to use sg_rtpg command to check the target port group asymmetric access state (aas).

Along with sg_inq command you can check if a specific disk (/dev/sdX) is in Active/optimized group or not.
