This behavior is okay in RHEV 3.6. In RHEV 3.6 vdsm's multipath config is used right from the beginning, and vdsm is configuring to always use mapper names - even for single path devices. For new 3.6 installations this should not be a problem. What about upgrades? On a machine where in RHEV 3.5 /dev/sd* was used, does the upgrade work to RHEV-H 3.6? Since during upgrades we cannot see the select page, so do we have another way to get the info which we want? The question is if upgrades are working, it is correct that you don't see the storage page. Upgrades is successful from rhev-hypervisor7-7.2-20151129.1 to rhev-hypervisor7-7.2-20160212.0 This is good news. For now I don't see a risk in this change of devices witha single path also appearing as mapper devices. The only visual change is in the TUI: In 3.5 there was /dev/[hs]d*, in 3.6 there will be /dev/mapper/.. But this is only visual and does not have a functional impact. |
