Is "pediags" useless for PE840's storage?

I have tested this now on PE840 with SAS5iR and DEBIAN LENNY 64bit. If SAS or SATA disks connected to SAS HBA should not make any difference for monitoring or tests.
./pediags sasdevdiag --show

You can see here that in DEBIAN LENNY standard installation the driver is not the actual one. And that there is no option to extract the a controller log.

OMSA 5.5 live also has SAS raid storage manager built in to query the SAS 5/6. That may give you more information as well.

============
You can see only 1 test is available, and when I run that test I get the error I wrote about in my initial post. It seems it will work only if you have SAS disks, while I have SATA.
I think this is kind of a bug, that having SATA disks disable even the controller log tests, controller self tests, ...
Thanks.

PEDIAGS is working properly and well on PE840 / 860 with SAS 5/6.
I will try to give a short explanation. For this I used OMSA 5.5 Live CD on a
PE2900 I with PERC5i but the behaviour is similar on SAS 5/6 (yes, I have
tested this). There is only one harddisk in SLOT 7 configured as RAID0 / VD0.
[root at anubis bin]# pwd
/opt/dell/onlinediags/oldiags/bin
[root at anubis bin]# ./pediags sasdevdiag --show
This command will give you a table like
Device Index : 1
Device Name : Dell PERC 5/i Integrated RAID Controller 1
Description : Dell PERC 5/i Integrated RAID Controller 1, Serial Number: <snip>
Device Class : RAID Controller
Device Status : Device is working properly.

Device Index : 6
Device Name : Array Disk 1:0:7
Description : SAS FUJITSU MAX3147RC
Device Class : RAID Array Disk
Device Status : Device is working properly.

Additional H/W Info : 139392 MB, Firmware: D207, Serial Number: <snip>

Test Name : Disk Self Test

In this table you can see the device which you could test and which kind of test is available.
[root at anubis bin]# ./pediags sasdevdiag --run test-index=all quicktest=true
>> /root/Desktop/results.txt
This would perform all tests but this is mostly not necessary. If you want to test one
of your harddisks pick the correct device number from list and perform only disk self
test.
[root at anubis bin]# ./pediags sasdevdiag --run device-index=6 test-index=1 quicktest=true

To extract the controller log from PERC5i you run
[root at anubis bin]# ./pediags sasdevdiag --run device-index=1 test-index=3
...

<snip>
Please take note that you cannot perform this on a SAS HBA as there is no
controller log.
Other steps will work on SAS HBA. Back to your question.

The result is onlya warning (informational) that he couldnt get infos from this
device in your configuration. This means not that all tests failed.
Please try with your harddisks only (where X is the disk device number from table).
[root at anubis bin]# ./pediags sasdevdiag --run device-index=<X> test-index=1 quicktest=true
