Hi Gleb,

I got a new kernel panic on 3.7
Kernel that we used is 5.4.200

this is scst.conf file:

# Automatically generated by SCST Configurator v3.7.0.


HANDLER vdisk_blockio {
        DEVICE lun1 {
                filename /dev/pool1/lun1
                size 10737418240000
                t10_dev_id a6dcc29e
                usn 61af3c146784a6dcc29e
        }
}

HANDLER vdisk_nullio {
        DEVICE device_null {
                dummy 1
        }
}

TARGET_DRIVER copy_manager {
        allow_not_connected_copy 1

        TARGET copy_manager_tgt {
                LUN 0 device_null
                LUN 1 lun1
        }
}

TARGET_DRIVER qla2x00t {
        TARGET 51:40:2e:c0:01:c2:a6:1c {
                HW_TARGET

                enabled 1
                rel_tgt_id 1

                LUN 0 device_null

                GROUP aac {
                        LUN 0 device_null
                        LUN 1 lun1

                        INITIATOR 50:01:43:80:74:ab:6f:c0

                        INITIATOR 50:01:43:80:74:ab:6f:c2
                }
        }

        TARGET 51:40:2e:c0:01:c2:a6:1e {
                HW_TARGET

                enabled 1
                rel_tgt_id 2

                LUN 0 device_null
        }

        TARGET 51:40:2e:c0:01:c6:54:38 {
                HW_TARGET

                enabled 1
                rel_tgt_id 3

                LUN 0 device_null
        }

        TARGET 51:40:2e:c0:01:c6:54:3a {
                HW_TARGET

                enabled 1
                rel_tgt_id 4

                LUN 0 device_null
        }
}

I am executing these commands for deleting aac group in a script file but I don't have any idea which one of below commands cause panic, and I am using these steps on 3.6 without any problems:

scstadmin -rem_init 50:01:43:80:74:ab:6f:c0 -driver qla2x00t -target 51:40:2e:c0:01:c2:a6:1c -group aac -force -noprompt

scstadmin -list_group aac -driver qla2x00t -target 51:40:2e:c0:01:c2:a6:1c

scstadmin --write_config /etc/scst.conf
scstadmin --list_device
scstadmin -close_dev lun1 -handler vdisk_blockio -force -noprompt
scstadmin --write_config /etc/scst.conf

and here is crash log:

I forgot to mention that I am using this option for qla2xxx_scst (in our san switch we should use target+initiator mode otherwise when we use exclusive as example if an initiator goes offline the session of it does not disappear)

options qla2xxx_scst qlini_mode=dual
