Tape array 5300 DVD common

I have a remote customer, rp5470 and rp2470 servers use same ,single DVD ROM in common; but I am not sure about connection setup ,even though I read lots of about 5300 similar posts here like daiys chain or single usage models..

there are two cluster (active inactive) = I mean 2 X 2 server + 1 DVD ROM ,both have same connection in cluster ,but one cluster sees DVD ROM from rp5470 other seems DVD ROM from Rp2470 server , DVD ROM on tape array 5300 no daisy chain connection. seems standard connection.

My rp5470 that doesn't see DVD ROM ,but RP2470 does see ,RP5470 is corrupted ,down and needs re-install , so I cannot do that ,due to DVD not visible connect..Besides , even though they have similar tape array connection ,on other cluster OR node RP2470 does not see DVD ROM ,but RP5470 is able to connect to DVD ROM ??

My question is where I have to look OR change what to make DVD ROM visible on down server ? SCSI ID switch ?

Second question ; when I copy boot disk with dd command to a new disk , then I put this new disk on corrupted server it will be work ? it will be bootable ?

Thanks in advance ,

Upon my second question: Second question ; when I copy boot disk with dd command to a new disk , then I put this new disk on corrupted server it will be work ? it will be bootable ?

dd is able to copy a disk content to another disk, does it mean if copying disk is boot disk , copied disk will be a boot disk ?
OR like in lvm mirror that makes second disk in mirror same with the active disk,should dd do that ?

DVD was not common, only thing I was wrong due to wrong answer from remote site that they said there was no internal DVD ROM, but in fact server has internal DVD ROM, then problem wrong explained here.
