Powerpath 5 is the only version of Powerpath which will work with RHEL4 U4.

Availablity mentioned in other thread: http://forums.emc.com/forums/thread.jspa?threadID=47682&tstart=0

I have used eLab Navigator and it seems that version 4.51 of Powerpath supports the latest RHEL4 Update 4, even with the latest kernel updates, at least in our case, so should I install 4.51 or wait untill the 5 is released?

Thanks in advance

I checked with engineering and I was wrong, PP 4.5.1 Does support RHEL4 U4

Documented in eLab Navigator "PDFs and Guides tab" -> "Infrastructure Software" -> "Powerpath"

i have been running into the same problem. i can not figure out if the version of powerpath is based upon the redhat update or the kernel version running on the machine. we have a redhat 4 AS u4 loaded on a machine that is still using the kernel from the original redhat install cd's. we can't seem to make anything work. some of the release notices seem to suggest that they assume that when you load the lasted redhat update, you should load the latest kernel and the version of powerpath and other software listed for that update is based upon the latest kernel. does anybody have any idea how to figure if the software (powerpath, etc.) is based upon the update number or the kernel version? please help if you can! i've been fighting this for two weeks now and can not get a good answer from anyone. THANKS!

Alfman, can you please post:

1) failed installation text exactly as it appears
2) kernel identification (I think its uname -r and the /etc/redhat-release file)
3) powerpath version

Thanks

kernel 2.6.9-5ELsmp
release Red Hat Enterprise Linus AS release 4 (Nahant Update 4)
naviagent 6.24.0.6.13-1
powerpath 4.4.0-343.rhel.i386

this is no error message as such. everything appears to load right, but when the agent is restarted, it just hangs. it never finishes starting. the system says the process is running but it is not. it also will not let us clean up all the rpm's. we have had to reload the OS several times.

we have also tried 6.24.1.5.0-1 and i believe a version of 4.5. the hba is a qlogic 2460 and with this we have tried v8.01.00-3 and a v8.00 variety. it always hangs the same way. that is why i am thinking that keeping the low kernel version with the higher updates may be confusing the rpm's we are trying to load.

That kernel is listed against PP 4.4 in the Powerpath Support Matrix at https://elabnavigator.emc.com/emcpubs/elab/esm/pdf/EMC_PowerPath.pdf

So you should open a case with EMC Support, as your configuration is supported.

Thanks!
i looked thru the reference guide. based on what i saw, i guess i can assume that what really matters in determining the needed software levels is not the actual upgrade level but the level of the kernel that you are running on that upgrade level. is this a valid statement? i have been fighting this so long, i would appreciate a short explaination if possible.

thanks again!!!

Yes its my understanding that only the kernel level really matters.
