The opposite holds true for TPG thereupon are, truly AO for LUN 2 and ANO for LUN 1.
On some active/passive ALUA-capable arrays, you may read port groups with a€?Standbya€? AAS rather than a€?ANOa€? on the non-owner SP.
Asymmetric Accessibility State
Harbors in an ALUA TPG are in the same AAS from start to finish regarding certain LUN. The TPG’s AAS tend to be reported into initiators in reaction with the REPORT TPGS order. The TPG descriptor try reported in byte 1 of this feedback.
Transitioning-The TPG AAS is in the procedure for switching from one condition to another. For instance, if the SP of an AO TPG is being rebooted or perhaps is taken traditional, or if perhaps the SAN (closet circle) admin manually transfers LUN ownership (on EMC CLARiiON, this might be generally trespass), the AAS in the TPG on the alternative SP adjustment to AO. While this procedure is actually ongoing luvfree App, the TPG AAS was transitioning.
As the TPG is actually this state, obtaining desires from initiators come back HECTIC or a CHECK DISEASE with feel key NOT EAGER and ASC (additional feel rule) PRACTICAL UNIT never OBTAINABLE or ASYMMETRIC ACCESS CONDITION CHANGEOVER.
