Pinned topic DLPAR: rhel5u3 removing memory : possible?

‏2009-06-26T11:42:54Z |
Hi!

We implemented some redhat-vio-clients both on a 9117-MMA(p570) and a E8A(p550). DLPAR-operations work, with one exception:

Removing memory is not possible

So, do you know, if it should be supported with 2.6.18-128-kernel of redhat?

It cannot be due to allocated memory, because we also installed a lpar with 70GB mem , and the os only used 1GB, and no applications were running

CAn you help us?

    The support for removing memory from an active system is not available in the RHEL 5 base, but was recently released and available in SLES 11. For some insights on the SLES 11 implementation, see the article on Using Active Memory Sharing on SLES 11

    Given that the support is in mainline, it's reasonable to expect that the Red Hat support will likely be integrated in a future version of RHEL, but it seems unlikely that the change would be integrated into a service update of RHEL 5.

    Hello!

    Thank you very much for the infos, it is a pity, that redhat can´t do it now

    best regards
