FC_BLOCK_SCSI_EH(9) SCSI mid layer FC_BLOCK_SCSI_EH(9)
NAME
fc_block_scsi_eh - Block SCSI eh thread for blocked fc_rport
SYNOPSIS
void fc_block_scsi_eh(struct scsi_cmnd * cmnd);
ARGUMENTS
cmnd
SCSI command that scsi_eh is trying to recover
DESCRIPTION
This routine can be called from a FC LLD scsi_eh callback. It blocks the scsi_eh thread until the fc_rport leaves the FC_PORTSTATE_BLOCKED.
This is necessary to avoid the scsi_eh failing recovery actions for blocked rports which would lead to offlined SCSI devices.
