https://community.hpe.com/t5/operating-system-linux/linux/m-p/4401826#M36113 Hello Yong,<BR /><BR />Our latest multipath issue resulted in no output with '-v2' as well, but it did not affect the functionality of multipath for us. All the paths still showed up in 'multipath -ll' and persisted across reboots.<BR /><BR />The difference between -v2 and -v3 are the verbosity levels. I do not know the exact differences between them.

Mine has the same problem. Can anybody tell me the difference? Man multipath only says "2 + print all info : detected paths, coalesced paths (ie multipaths) and device maps".<BR /><BR />Waht is the result of these commands.?<BR /><BR />I use RH Linux 5.3, kernel 2.6.18-92.1.22.el5.<BR /><BR />Yong Huang Thu, 16 Apr 2009 06:38:57 GMT https://community.hpe.com/t5/operating-system-linux/linux/m-p/4401825#M36112 sen_ux 2009-04-16T06:38:57Z https://community.hpe.com/t5/operating-system-linux/linux/m-p/4401826#M36113 Hello Yong,<BR /><BR />Our latest multipath issue resulted in no output with '-v2' as well, but it did not affect the functionality of multipath for us.
