Red Hat Bugzilla – Bug 170153
Pool and multipathing with Hitachi software.
Last modified: 2010-01-11 22:08:02 EST
Description of problem:
Pool attempts to do its own multipathing using underlying devices and the HP
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use pool on top of 3rd party multipath software device
If a device has two paths (A and B) and using third party software creates a
third path (M) which does multipathing between A and B, pool erroneously does
its own multipathing between A,B, and M instead of simply going through M.
Pool should sit ontop of the single multipathed device.
Fixed for HP multipath software.
It was not HP, it was Hitachi
