I have Linux red-hat 5.5 cluster machine that connected to EMC storage

When I perform

    powermt display

command I see under dead line the number 1

In place to get normal state as 0

Please advice what this is mean? problem with Fiber channel or card ? what can be else ?

What need to check in the navyspare GUI ? or maybe run other navicli command for more verification?
