IBM Datapower on Linux

DustinB3403

Does anyone have any experience with Datapower on Linux?

Simply put, it should be an installation through RPM, which I have all of the RPM. What I'm getting hung up on is the LUKS partitions which are apparently required, but not specified what needs to be done to configure these.

From IBM:

Resource requirements on Linux hosts
To install the DataPower Gateway, the host must meet the following requirements.
To install the RPM packages, the host must be running a supported 64-bit version of Linux.
2 GiB of free storage must be available on /opt.
5 GiB of free storage must be available on /var.
At least two free loop devices are needed, with another loop device when RAID storage is used.
RAID storage, if used, must be configured in the datapower.conf file.

I'm not using raid, here I'm showing the disk layout and the loop devices.

The installation which is a simply yum install xxx.image.x86_64.rpm xxx.common.x86_64.rpm

Which I then should have a stopped "datapower.service", but the service keeps crashing because it's looking for these LUKS partitions.

I've never dealt with Datapower, but I suspect there's a configuration file related to datapower-control that may need some editing.

@EddieJennings said in IBM Datapower on Linux:

So there is a configuration file, but there is no reference at all within the conf file (/var/ibm/datapower/datapower.conf) regarding the LUKS partition.

Never had the privilege to deal with Datapower on Linux. Though it looks very interesting.
