If you error: cannot open powerpath. initialization error rhel7 have a better answer, by all means share it with us. Q. I was working on an AIX host when I encountered "Initialization Error." when running "powermt display". This error is present when running as sudo. But I tried running as root, hoping things would be different as super-user but that was not the case. The errors I encountered are

Even as the super-user "root", the error was persistent. I'm not that very well versed with AIX, so I tried using a command that was always useful in Solaris -- truss. I then hit jackpot! This is the output of the command. root@host > truss powermt display execve("/usr/sbin/powermt", 0x2FF22C94, 0x2000FB38) argc: 2 __loadx(0x03480000, 0x2FF22A70, 0x00000140, 0x10000000, 0x2000033D) = 0x00000000 __loadx(0x0C000000, 0xF020AABC, 0x00000000, 0xF0317004, 0xF020A460) = 0x00000000 thread_init(0x0000000000000000, 0x00000000D0117CCC) = sbrk(0x00000000) = 0x20018404 vmgetinfo(0x2FF22978, 7, 16) = 0 sbrk(0x00000000) = 0x20018404 vmgetinfo(0x2FF22440, 7, 16) = 0 sbrk(0x00000000) = 0x20018404 sbrk(0x0000000C) = 0x20018404 __libc_sbrk(0x00000000) = 0x20018410 getrpid(-1, -1, -265185236) = 253984 _getpid() = 253984 getprocs(0x20018ED8, 920, 0x00000000, 0, 0xF03173B0, 1) = 1 appulimit(1005, 0) = 0x20029000 _thread_self() = 610395 thread_setmystate(0x00000000, 0x2FF225D0) = 0 thread_setmystate(0x2FF222C0, 0x2FF225C8) = 0 _sigaction(3, 0x2FF228F8, 0x2FF22908) = 0 _sigaction(4, 0x2FF228F8, 0x2FF22908) = 0 _sigaction(5, 0x2FF228F8, 0x2FF22908) = 0 _sigaction(6, 0x2FF228F8, 0x2FF22908) = 0 _sigaction(7, 0x2FF228F8, 0x2FF22908) = 0 _sigaction(8, 0x2FF228F8, 0x2FF22908) = 0 _sigaction

PowerPath is required to use efficiently two EMC array (one is local site, other is remote site). Remote paths (called X-connect) must be set in standby mode (maybe possible and difficult withlinux native multipathing), due to overhead latency. More information in a PDF (EMC web site).
