Testing a 16 SATA drive (/dev/sd[c-r]1), md RAID, with drives installed
in a hotswap SAS/SATA enclosure.
Failed out /dev/sdd1, ejected the drive from the enclosure, reinserted
it and the system added it back as /dev/sds:

Rebooting shows the offline drive back as /dev/sdd.
Is there a safe, (OK to do on a mounted, active array), way of changing
the sds back to sdd, prior to adding it back into the array, without
having to reboot?
Regards,
Richard
