Have an XServe RAID hooked up to a Dual 2ghz G5 via Apple Fibre Channel card. The XServe volume is mounted on the G5 (Running OS X 10.3 Server). If I try to copy a bunch of files at once (Folder comprising at least 1,000), it seems like I lose the Fibre link between the XServe and the G5.. when I start the copy, the disk activity lights show disk activity, but after a moment (seemingly random), the activity indicator will go dark on the XServe RAID, and the copy operation will hang in the finder. Sometimes, I even lose the indicator on the XServe RAID for the Fibre Channel link.. so it seems like after a seemingly random time period of data transmission, something weird happens to the Fibre link. Attempted to copy the files using 'cp' through the terminal, and got the same results.
Does this make sense to anyone? I tried a few things to troubleshoot: I replaced the Fibre card with another one to make sure it wasn't the card.. that didn't help. Made sure both the XServe RAID and the Fibre Channel card were set to Point to Point topology (For some reason, they keep wanting to go to Arbitrated Loop if set in auto.. any reason why?? I seem to have the issue whether they're both in PtP or Arbitrated Loop.. so that's not the issue.)
This is especially frustrating.. because while I can copy one or two files over at a time, any respectable amount of files copied at once just kill the Fibre link between the system and the XServe.. and I can't kill the copy operation either.. it'll just sit there blissfully unaware and not moving anywhere until I give the machine a hard reboot. XServe volume is formatted in Journaled HFS+.. haven't tried plain HFS+ yet, think that might help the issue?
