IBM Power Ideas Portal

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:

Post your ideas

Start by posting ideas and requests to this portal to enhance a Power product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas and add comments to ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The Power teams will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Add more libraries emulation support to "ISCSI attached VTL" feature

We have tried to attach QUADSTOR VTL and Starwind VTL to IBM i using ISCSI and with the listed PTFs in place with no luck. But we have found the IBM i could login to the Starwind virtual device, but never showed the IBM i device. Can you add the same "drivers" on IBM FC attachment to the ISCSI feature? This will allow an easier transition to the cloud, for example: PowerVS

    The CAAC has reviewed this requirement and recommends that IBM not implement this request. The vendor should emulate the IBM hardware as other vendors have successfully done.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    Its probably the firewall on the VTL which is preventing the connection and not the distribution. Try with firewall disabled, or try telnet 3260 to see if you can make a connection to the VTL iscsi daemon port. Try with the latest version of the quadstor vtl.

    Quadstor runs perfect on FC which (as general view) also allows Save21 in restricted mode and IPL.

    PTFs are un placer. With Starwind VTL the connection was possible. With Quastir VTL wasn't, but maybe there's something wrong on my Linux security. Thanks for your post, will try with different distribución.

    IBM i can connect to quadstor vtl devices over iSCSI. @Guest maybe you havent installed alll the correct PTFs or maybe you haven't configured the connection correctly.

    .IBM i is not an open attach 3rd party storage platform. The tape device drivers are the same on both iSCSI and FC. The 3rd party vendor if they choose to attach has to support what is provided for both the protocol stack and device emulation. IBM will consider this request to add support and work with these vendors.
