Often questions arise how many paths to a LUN are supported or recommended. Or if there is a minimum number of paths required or a maximum number of paths allowed for SDD/SDDPCM devices on AIX?
The first source should be the appropriate Multipath Subsystem Device Driver User's Guide
e not supported.
marginal links involve the connection between the switch and the edge device. Isolating the exact cause of a marginal link involves analyzing and testing many of the components that make up the link (including the switch port, switch SFP, cable, the edge device, and the edge device SFP).
Business Value of Solution: Quick response time in situations where SVC performance utilization needs to be assessed.
