Hi,

I'm trying to install PowerPath package on a SLES9.0 SP1 32Bits
machine. According EMCpowerlink website, I must use latest version of
PowerPath which is:

EMCpower.LINUX-4.4.0-343.sles.i386

But installation failed complaining as follow:

------------------------------
house2:~/SAN/PowerPath/v4.4.0 # rpm -ivh
EMCpower.LINUX-4.4.0-343.sles.i386.rpm

My machine is running SP1 *only* and complies with EMC requirements:

----------------------------
house2:~/SAN/PowerPath/v4.4.0 # SPident

CONCLUSION: ServicePack Level: SLES-9-i386-SP1 => up-to-date
----------------------------

My HBA drivers appears to be good an up to date for SLES9.0 SP1

---------------------

Also, I can say that I have the same trouble with a second machine
running SLES9.0 SP2 this time and get exact same error message. With
SLES9.0 SP2, the default QLA driver is 8.00.02 but produce exact same
error.

Does anyone knows why PowerPath complain about Driver version mismatch
and how to solve this ?

This error comes up when PowerPath encounters an unsupported version of
the SUSE Kernel.
Ensure that your particular Kernel version is supported by checking the
EMC Support Matrix

Exact. But here is the funny part. EMC claims support for SLES9 SP1
which is running kernel revision 139. OR looks what's happen when you
switch the installation of the RPM verbose enough:

Have a closer look above and notice the condition:

2.6.5-7.151-smp SMP 586 REGPARM gcc-3.3' = '2.6.5-7.139-smp SMP 586
REGPARM gcc-3.3

You are not dreaming. For EMC, a SLES9 SP1 is a machine having kernel
revision 151 !!! And they are not saying anything about anywhere !!!

After loaded this kernel revision, everything is ok. But why claiming
support for SP1 then ?

Thanks Conor.

According to the EMC PowerPath Compatiblity Matrix, the minimum kernel version is 2.6.5.7-151.
I have just installed a new SLES9 server, with SP1 (kernel 139) and upgraded the kernel to the latest version available: 2.6.5.7-201

PowerPath installation still gives a magic mismatch - this is apparently because EMC ONLY support the 151 release and NOTHING else!

So if I wish to run a better, safer more reliable environment or certain applications require a kernel version higher than which EMC has specified, I have two choices: 1, no PowerPath or 2, No application /reduced stablity etc.

Personally I would even go as far as throwing the SAN out - certainly one supplied by EMC. Sadly the choice is not mine to make! Evil or Very Mad
