Subject: mpt2sas: device_blocked question
Date: Sat, 26 Jan 2013 11:52:14 +0800	[thread overview]

Hi,
  we encounter a problem that a disk is blocked forever, the key log is:

mpt2sas0: TEST_UNIT_READY: handle(0x000a), lun(0)
mpt2sas0: TEST_UNIT_READY: handle(0x000a), lun(0)
mpt2sas0: Spinning up disk.... handle(0x000a), lun(0)
mpt2sas0: TEST_UNIT_READY: handle(0x000a), lun(0)
mpt2sas0: Spinning up disk.... handle(0x000a), lun(0)
mpt2sas0: TEST_UNIT_READY: handle(0x000a), lun(0)
mpt2sas0: Spinning up disk.... handle(0x000a), lun(0)
sd 2:0:1:0: device_blocked, handle(0x000a)

  looking into the driver code, it seems that the device is blocked by function 
_scsih_block_io_to_children_attached_directly() in mpt2sas/mpt2sas_scsih.c
with reason_code == MPI2_EVENT_SAS_TOPO_RC_DELAY_NOT_RESPONDING,
  what does this reason_code mean please? when should it be returned? and any way to handle it?

Best Regards,
spren
