Restrictions and Known Problems

  • The rpm package conserver-xcat was added in the dependency package to replace conserver. If encountering the issue that conserver-xcat conflicts with conserver when updating of xCAT from 2.6.9 to 2.7, remove the conserver manually first and try again.
  • When powering on multiple p775 CECs or powering on LPARs of multiple p775 CECs via rpower, set site.powerinterval to 30 before running rpower. See https://sourceforge.net/tracker/?func=detail&aid=3426911&group_id=208749&atid=1006945 for details.
  • The rnetboot command for p775 LPARs won't correctly set the default bootlist in AIX diskless nodes so the LPAR can be rpower'd next time. Also, the default bootlist can sometimes change after the user sets it. The workaround for now is to always run rbootseq before running rpower on for p775 LPARs. See https://sourceforge.net/tracker/index.php?func=detail&aid=3435969&group_id=208749&atid=1006945 for details.
  • AIX is shipping it's own chdef and psh command in AIX 7.1.1. With normal installation they fall first in the path, so you may be surprised by the fact your man page and command are not what you expect when you run chdef of psh. You are going to need to update your profile to put the xcat paths before the OS chdef and psh, and also modify the MANPATH to put the xCAT man page first. https://sourceforge.net/tracker/?func=detail&aid=3424615&group_id=208749&atid=1006945
