Solution Verified - Updated -

Issue

  • We have server which configuration with external storage needs to be corrected. Server is connected with two HBA cards to HP EVA5000 storage array but there is no multipathing software on server installed/configured. It of course leads to problems when storage switching between controllers, SAN maintanace is performed etc.

  • So, I would like to know procedure for implementing correct device-mapper multipath solution here?
