Yes, it is bad - a decision has been made to replace these disks with
"enterprise"-versions (without TLER/ERC problems etc). Tw_cli produces
this output for the volume:

# tw_cli /c0/u0 show all
/c0/u0 status = OK
/c0/u0 is not rebuilding, its current state is OK
/c0/u0 is not verifying, its current state is OK
/c0/u0 is initialized.
/c0/u0 Write Cache = on
/c0/u0 Read Cache = Intelligent
/c0/u0 volume(s) = 1
/c0/u0 name = xxx
/c0/u0 serial number = yyy
/c0/u0 Ignore ECC policy = off
/c0/u0 Auto Verify Policy = off
/c0/u0 Storsave Policy = protection
/c0/u0 Command Queuing Policy = on
/c0/u0 Rapid RAID Recovery setting = all
/c0/u0 Parity Number = 2
