HP X5520 G2

[Luke_Y]

Hello.

i have HP X5520 G2 .

i have replaced 2 failed drives on bay 23 and bay 30 

both of them are in green but the other disks went to health degraded (visible in storage viewer).
on another note after i opened the shelf drawer and replaced the disks

i cant close it again as if something in the way blocking it

when trying to slide it back one of the cards  sticking out.

my question is this ....can i completley shutdown the 2 controllers check it and boot it up

and there wont be an issue ?

are there any specific things i need to check before shutting it down ?

thank you in advance.
