Fix RMC connection
There are some basic commands that can be run to check status of RMC configurations and there are some dependancies on RSCT versions as to which commands you use. RSCT 3.1.x.x levels are the newest and included in AIX 6.1 TL6 or higher and RSCT 2.x.x.x are included in AIX 6.1 TL5 or lower. Following queries provide a quick method to assess RMC health.On AIX 6.1 TL5 or lower, this fileset needs to be installed
lslpp -l csm.client
On AIX 6.1 TL6 or higher, his fileset needs to be 3.1.0.x level or higher
lslpp -l rsct.core.rmc
On all AIX versions, check if all IP and host IDs trusted.
/usr/sbin/rsct/bin/ctsvhbac
check if HMC are listed as a resource
For AIX 6.1 TL5 or lower
lsrsrc IBM.ManagementServer
For AIX 6.1 TL6 or higher
lsrsrc IBM.MCP
On HMC (as hscroot) check LPAR's DCaps value are non-zero
lspartition -dlpar
If you answer no to any of the above then corrective action is required.
Connections can be fixed with commands (run as root on LPAR, HMC, or both) below:
/usr/sbin/rsct/install/bin/recfgct /usr/sbin/rsct/bin/rmcctrl -p
You would need a pesh password for your HMC if you need to run the above fix commands on the HMC.
You can try the following command first as hscroot:
lspartition -dlparreset
If that does not help you will need to request pesh passwords from IBM Support for your HMC so you can run the recfgct and rmcctrl commands listed above.
After running the above commands it will take several minutes before RMC connection is restored. The best way to monitor is by running the lspartition -dlpar command on the HMC every few minutes and watch for the target LPAR to show up with a non-zero DCaps value.
Connect to LPAR using vterm
mkvterm -m [ManagedSystem] -p [LparName] mkvterm -m [ManagedSystem] --id [Number] rmvterm -m [ManagedSystem] -p [LparName] rmvterm -m [ManagedSystem] --id [Number] ~~. |
open a vterm by LPAR Name open a vterm by LPAR ID close a vterm connection by LPAR Name close a vterm connection by LPAR ID logout from vterm session |
