[Multipathing] Incorrect host multipathing status #3956

Closed badrAZ closed 5 years ago

badrAZ commented 5 years ago

To check if the multipathing is enabled on a host, we use a property which only available on hosts with XenServer >= 7.5.

I believe the info only relates to iSCSI although the way the info is being presented it's really not obvious at all. At first we thought it was multipathing as a whole including HBA type. As such "disabled" status didn't made any sense as it does hows enabled on xencenter and using the command line:

xe sr-param-list uuid=d32f4722-9d3c-5412-ce94-8c678e447a02 | grep -i mul
sm-config (MRO): allocation: thick; use_vhd: true; multipathable: true; devserial: scsi-360002ac0000000000000001c00012157

The way the info is being presented is really not obvious and creates confusion on the status of things. I strongly suggest reviewing this in order not to create false positives...

Note, using XenCenter 7.1 CU1 and CU2 (same behaviour) with XOA 5.31.2

Hi, thank you for your feedback.

The multipathing status displayed in XO is not related to the SR but to the host.

In the current version, the host multipathing status is not correct for XS with version < 7.5 because we used a property that was not provided on the old XS versions. But it will be fixed for the next release.
