1. When /run/bm-drive-cleaning-done.flag is present, it means cleaning
is done and we are in BM_MODE. Also, it is acked by renaming flag to
bm-drive-cleaning-done-ack.flag
2. if not case 1, when /run/bm-drive-cleaning-done-ack.flag is present,
it means the cleaing is done and acked
3. if not case 2, when bm-ready.flag is present, it means we are in
BM_CLEANING_MODE. /run/bm-drive-cleaning.flag is created if needed
4. otherwise, we are in NON_BM_MODE
Tested:
bm-ready.flag is not present. Respond Non-BM mode:
ipmitool raw 0x2e 0x32 0x79 0x2b 0x00 0x10
79 2b 00 10 00
bm-ready.flah is present. For next call, respond Cleaning Mode and
bm-drive-cleaning.flag is created:
ipmitool raw 0x2e 0x32 0x79 0x2b 0x00 0x10
79 2b 00 10 02
keep responding Cleaning Mode until bm-drive-cleaning-done.flag is
created. So cleaning is done and for next call, respond BM mode and
rename bm-drive-cleaning-done.flag to bm-drive-cleaning-done-ack.flag:
ipmitool raw 0x2e 0x32 0x79 0x2b 0x00 0x10
79 2b 00 10 01
