I guess you havent connected the cable to that adapter port so you are getting these errors / no reason for concern

3 
pcmpath query device

And check if you are using to those adapters for disks path
lsdev - nad check if you are using those for tape drives

if answer is "NO" I agree zxmaus - nothing worry about
If answer is "YES"

  1. do Diag on adapter maybe it is broken
  2. contact your SAN to SAN do switch checking
  3. Check compatybility matrix for storage, SAN switch, sddpcm, adapter firmware and box Microcode.
  4. Try to move cable to different SAN port on switch
  5. Replace the SAN cable
  6. Open Hardware call and replace the adapter
