    Too many disks after array connected


    I have connected array/storage (with 2 volumes created on it). Its HP P2000 MSA if it matters,

    By connecting storage I was expecting to see just 2 new disks:
    Code:
    /dev/sdb 
    /dev/sdc
    However, instead of just 2 new disks I see way more.
    It looks that somehow /dev/sdb and /dev/sdc are duplicated many times. Disks sdd,e,f,g,h,i representing in fact /dev/sdb and /dev/sdc.
    Code:
    # cat /proc/partitions
    major minor  #blocks  name
    
       7        0     466902 loop0

    Does anyone understand what is happening here ?

    I've seen this before and can't remember the explanation, some about showing all the potential LUNs even if unused.
