tcm_qla2xxx jam_host attribute
|
|
------------------------------
|
|
There is now a new module endpoint atribute called jam_host
|
|
attribute: jam_host: boolean=0/1
|
|
This attribute and accompanying code is only included if the
|
|
Kconfig parameter TCM_QLA2XXX_DEBUG is set to Y
|
|
By default this jammer code and functionality is disabled
|
|
|
|
Use this attribute to control the discarding of SCSI commands to a
|
|
selected host.
|
|
This may be useful for testing error handling and simulating slow drain
|
|
and other fabric issues.
|
|
|
|
Setting a boolean of 1 for the jam_host attribute for a particular host
|
|
will discard the commands for that host.
|
|
Reset back to 0 to stop the jamming.
|
|
|
|
Enable host 4 to be jammed
|
|
echo 1 > /sys/kernel/config/target/qla2xxx/21:00:00:24:ff:27:8f:ae/tpgt_1/attrib/jam_host
|
|
|
|
Disable jamming on host 4
|
|
echo 0 > /sys/kernel/config/target/qla2xxx/21:00:00:24:ff:27:8f:ae/tpgt_1/attrib/jam_host
