# SPDK iscsi_tgt test plan
|
|
|
|
## Objective
|
|
The purpose of these tests is to verify correct behavior of SPDK iSCSI target
|
|
feature.
|
|
These tests are run either per-commit or as nightly tests.
|
|
|
|
## Configuration
|
|
All tests share the same basic configuration file for SPDK iscsi_tgt to run.
|
|
Static configuration from config file consists of setting number of per session
|
|
queues and enabling RPC for further configuration via RPC calls.
|
|
RPC calls used for dynamic configuration consist:
|
|
- creating Malloc backend devices
|
|
- creating Null Block backend devices
|
|
- creating Pmem backend devices
|
|
- constructing iSCSI subsystems
|
|
- deleting iSCSI subsystems
|
|
|
|
### Tests
|
|
|
|
#### Test 1: iSCSI namespace on a Pmem device
|
|
This test configures a SPDK iSCSI subsystem backed by pmem
|
|
devices and uses FIO to generate I/Os that target those subsystems.
|
|
Test steps:
|
|
- Step 1: Start SPDK iscsi_tgt application.
|
|
- Step 2: Create 10 pmem pools.
|
|
- Step 3: Create pmem bdevs on pmem pools.
|
|
- Step 4: Create iSCSI subsystems with 10 pmem bdevs namespaces.
|
|
- Step 5: Connect to iSCSI susbsystems with kernel initiator.
|
|
- Step 6: Run FIO with workload parameters: blocksize=4096, iodepth=64,
|
|
workload=randwrite; varify flag is enabled so that
|
|
FIO reads and verifies the data written to the pmem device.
|
|
The run time is 10 seconds for a quick test an 10 minutes
|
|
for longer nightly test.
|
|
- Step 7: Run FIO with workload parameters: blocksize=128kB, iodepth=4,
|
|
workload=randwrite; varify flag is enabled so that
|
|
FIO reads and verifies the data written to the pmem device.
|
|
The run time is 10 seconds for a quick test an 10 minutes
|
|
for longer nightly test.
|
|
- Step 8: Disconnect kernel initiator from iSCSI subsystems.
|
|
- Step 9: Delete iSCSI subsystems from configuration.
