Hi experts!

Our server infrastructure now contains a new P550 with 2 HBA cards that will connect to a new SAN (DS4700) through a SAN switch. The server OS is Red Hat Enterprise Lunux Advance Server 4 Update 4.

We are trying to install the RDAC driver on our system but is failing during the
build process (make clean is ok; make is failing)

Below an extract of the error message:

hi,

Got the solution from the IBM Developer Works forum:

http://www.ibm.com/developerworks/fo...=166118&cat=53


glibc-devel.ppc64 was not installed installed.

kind regards

Can I ask if multipathd in RHEL is an option? We've been using that on our X Series Linux Servers with great success (providing you're at U4). Also, it's much easier to upgrade than RDAC/SDD.

Sorry if it's a stupid question, we don't do anything with Linux on Power.
