| Testcase Number |
Test Procedure |
Expected Results |
| 1 |
Verify that disconnecting the power from disk1 will
keep the system running healthy.
- Boot system with two disks connected.
-
cat /proc/mdstat shows the two disks working in
raid-1 mirror.
-
Remove power cable from disk1 while the system
is running.
|
-
Ensure the system is still responding, and you
can still read and write to the disk.
-
Also, ensure an error message in
/var/log/messages indicating one of the disks is
off-line.
-
If you have event logging installed, then look
for event logger error (event_type=1021) using
evlview -filter 'event_type=1021'.
|
| 2 |
Verify the system can boot from disk2 (the only
connected disk).
-
Before you do this step, make sure that lilo is
set to boot from /dev/mdx device and not the sd
device (boot=/dev/sdx).
- Boot system after test case 1.
|
-
Verify the system reboot all the way with no
problem.
-
System responds to I/O commands after
boot.
|
| 3 |
Verify the system boots from disk 1 only (disk 2
disconnected).
-
Before you do this step, make sure that lilo is
set to boot from /dev/mdx device and not the sd
device (boot=/dev/sdx).
-
Take the system down (normal
shutdown).
-
Disconnect the power from disk2 and connect it
to disk1.
|
-
Verify the system reboot all the way with no
problem.
-
System responds to I/O commands after
boot.
|
| 4 |
Verify that re-connecting the power to disk 1 and
disk 2 will keep the system running healthy.
- Shut down.
-
Re-connect the power cable to the disk was
removed (connect both disks).
- Bring the system up.
|
- Verify the system comes up healthy.
-
The OS sees both disks using "fdisk
-l".
-
One of the raid disks is attached (cat
/proc/mdstat).
|
| 5 |
Verify that you can bring the system to a healthy
raid state after re-connecting both disks.
-
After case 5, run raidhotadd on all partitions
of the inactive disk. (e.g. raidhotadd /dev/md0
/dev/sdb1).
|
-
cat /proc/mdstat shows remirror is in
progress.
-
Once completed, cat /proc/mdstat will show two
disks are active.
-
Verify the system still healthy (can write/read
to disk).
|
| 6 |
Verify that inserting a new disk will keep the
system running healthy.
- Take system down (normal shutdown).
-
Connect a new secondary disk (disk 3) to the
system along with one of disk 1 or disk
2.
- Boot system.
|
-
The OS sees two disks using "fdisk
-l".
Note: If hot-insertion feature supported, skip
test case 6,7,8,9.
|
| 7 |
Verify that you can bring the new disk to a healthy
raid 1 system.
-
Partition the disk to the same size of the
active disk.
- Run raidhotadd on each partition.
|
-
Check /proc/mdstat shows the new disk is being
added to raid-1.
-
All partitions will copy with no
problem.
|
| 8 |
Verify that the system can reboot after copying all
data to disk 3.
- Update lilo (/sbin/lilo).
- Reboot the system with both disks.
|
-
Verify the system reboot and comes up with two
raid disks are attached. (cat
/proc/mdstat).
|
| 9 |
Verify that the system can reboot from the new
inserted disk only (disk 3).
-
Take the system down (normal
shutdown).
-
Disconnect power from disk 2 or 1, and leave
the power connected to disk 3, then bring the
system up.
|
-
Verify the system reboot all the way with no
problem.
-
System responds to I/O commands after
boot.
