DLPAR动态磁带机不能划分的问题的解决方法

Subsystem	Group	PID	Status
ctrmc	rsct	21044	active
IBM.CSMAgentRM	rsct_rm	21045	active
IBM.ServiceRM	rsct_rm	11836	active
IBM.DRM	rsct_rm	20011	active
IBM.HostRM	rsct_rm	20012	active

IBM.DRM and IBM.HostRM are "lazy started" resource managers; they're only started when they get used. If IBM.DRM and IBM.HostRM are inoperative, there's a good chance you're having network/hostname setup problem between HMC and the LPAR. To correct this, see Table 3. Verify Your RMC/DLPAR setup, below.

If AIX is 51G, 52B or above, ctcas is also a lazy started RM, meaning it can stay inoperative until they get used, so it's not necessary to start it if your LPAR is at these levels or later.

If any of the daemons show as inoperative, use > startsrc -s . For example, startsrc -s IBM.CSMAgentRM。

--------------------

以上重启若还有问题的话，用以下命令重启整个rmc daemon

Refresh RMC by either rebooting or

  > /usr/sbin/rsct/bin/rmcctrl -z
  > /usr/sbin/rsct/bin/rmcctrl -A
