A possibility is that there were multiple control paths defined in the
3584 library.

This can be adjusted via the 3584 front panel LCD, or I think, also the
web interface (though I never used it much due to the infamous 3584
ethernet issues).

The 'Other FC SCSI...' looks odd, though. Does the system have Atape
installed? And the drives are IBM LTO drives?

Could be that rmt4-6 was seen before additional control paths were
defined, because once you have additional CPs, your view of the drives
contained in them can be blocked.

Ultimately, I think you want to determine if the 3 CPs is what you want.
If not, needs to be set back to the default one CP for entire library.

You'll also want to figure out why the LTO tape drives aren't showing up
right if they're IBM LTO tape drives.

Another thing to triple check with the 3584, in my experience, is to
ensure the drives, library, and FC adapter microcode are all at the
latest available and stable revision.

If you're still stuck, even after adjusting all these as desired, then
please describe the 3584 setup (1 L32 and how many D32s, how many
drives, what type of drives and their mfr, microcode revs for library,
drives, and FC adapter, what FC adapter, what host type/model, what host
OS and version is running, level of Atape installed, etc.
