Hi Hans,

> Thanks! I've filed bug for this: https://www.illumos.org/issues/16277

reguarding your bug report,  I had just plugged in a new disk before expanding my pool from two disks to four, and I did this as soon as the system reached the login: prompt after a reboot.

When I inserted the second one, nothing happened.

Thursday I'll be able to try to add a new disk right after a reboot to see if I can cause the problem again.

Btw,

> char [128] evt_descr = [ "Inserted: Drive 02(e252/Port 1I Box 0 Bay 0)" ]

My unit has a single SFF disk cage which can hold 8 disks, I did insert mine into slot 5 or 6, but as you can see it shows Bay 0, which is wrong; the cage has disks numbered from 1 to 8, from left to right.

This is the cage: https://www.servershop24.de/en/hpe-sff-gen9-gen10-cage/a-117573/

Thanks, I'll let you know if I can break it again ;-)

Maurilio.
