mpt2sas/sd_mod: Adding back a removed disk handle

One of my disks had a slight hiccup. This caused mpt2sas to remove the
handle to the disk. In my kernel log I get:

mpt2sas1: removing handle(0x0021), sas_addr(0x500304800182694c)

By reseating the disk physically I can get mpt2sas to pick up the disk
again, but can I somehow through software ask mpt2sas to detect the
drive again without physically reseating the drive?

I tried:

parallel 'echo "- - -" >' ::: /sys/class/scsi_host/host*/scan

but that did not pick up the drive.

The drive is sitting in an enclosure
