IBM Power Ideas Portal
This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
Shape the future of IBM!
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Search existing ideas
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post your ideas
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.
Specific links you will want to bookmark for future use
Welcome to the IBM Ideas Portal (https://www.ibm.com/ideas) - Use this site to find out additional information and details about the IBM Ideas process and statuses.
IBM Unified Ideas Portal (https://ideas.ibm.com) - Use this site to view all of your ideas, create new ideas for any IBM product, or search for ideas across all of IBM.
ideasibm@us.ibm.com - Use this email to suggest enhancements to the Ideas process or request help from IBM for submitting your Ideas.
IBM has evaluated the priority of this enhancement proposal relative to other future product content and determined that this RFE will not be pursued for a future product release
Josh,
I missed seeing your comments. Please see what has been documented in EMC Publication and this is what the current issue at our client site.
PowerPath and the bosboot tool
After a system boots from a PowerPath device, the bosboot tool cannot function correctly.
This is because of the state of the configuration after booting from a PowerPath device and
the fact that bosboot expects the boot device to be an hdisk, not an hdiskpower device.
The pprootdev fix command corrects the configuration to allow bosboot to work. Run
pprootdev fix before undertaking any administrative task that runs bosboot. This corrects
the configuration for bosboot but does not change the PowerPath boot switch. The next
system boot still uses PowerPath. Run pprootdev fix only once after the system that uses
PowerPath restarts. bosboot then functions correctly until the system restarts again.
Note: Always use the command bosboot -ad /dev/ipldevice to create a boot image from
the current boot kernel disk.
If a PowerPath device is the boot device
If your previous PowerPath version uses a PowerPath device as the boot device, disable
multipathing to the root device before upgrading.
1. Run pprootdev off.
2. Restart the host.
After upgrading, enable multipathing to the root device again:
1. Run pprootdev on.
2. Run pprootdev fix and bosboot-ad /dev/ipldevice.
3. Reboot the host.
This functionality already exists. AIX natively supports MPIO, and EMC provides an ODM fileset to improve EMC MPIO support.
Powerpath specifically disables MPIO, and all functionality there, including porootdev and the risks there, are a part of EMC bypassing AIX's MPIO.
