Hello,
we have a P6 System with VIOS Version: 2.2.0.12-FP24 SP-02 (vio0-p6 / vio1-p6)
P6 Firmware: 01EM350 IPL: 118

HMC Version: V7R7.4.0 + SP2 Build Level: 20120328.1

P740 with: VIOS Version: 2.2.1.4 (vio0-p740 / vio1-p740)
P740 Firmware: 01AL740 IPL: 88

All SAN disks are available on all VIOs. (But on the older VIOs we have native MPIO+SDDPCM the newer one do have native MPIO)
the older LPARs moved to new Strorage System (native MPIO)

If i create an empty LPAR on the Power6 System and start a Migration
I get the Error: HSCLA246

HSCLA246 The management console cannot communicate with partition vio0-p740. Either the network connection is not available or the partition does not have a level of software that is capable of supporting this operation. Verify the correct network and setup of the partition, and try the operation again.

Processor compatibility mode: Power6 of the LPAR
If i create a LPAR on the Power7 System (in Processor compatibility mode: Power6 too)
and try to move this LPAR to the Power6 System i get the same error

Do you have any ideas what might be the cause for this problem?

Thanks

Hi Tux, there are a lot of causes to get this error, the more common are:

• The VIOS servers have connectivity with HMC? you could test if the connection is available trying to add/remove hardware in a dynamic logical partition way (DLPAR operation).

• The VIOS servers no have connectivity with the lpar (test with ping and ssh).

• The OS of lpar not support lpm...(oslevel -s)

Tell me what you check and we could continue troubleshooting

Hi,
the Problem was that the 2nd vios was a 1:1 copy of first vios.
After newinstall the 2nd vios all was running.
There are some unique id´s. That was the Problem.
So the HMC only communicate with the last started vios.
Because the HMC belive that the VIOs is now on a other LPAR.
Thanks

Hi Tux,

 

What was the fix for this?  I'm getting the same behavior after I cloned and LPAR.

 

Thanks

hi,

sorry my only solution was a newinstall of the VIOS so that the 2 VIOs not from the same install(clone).

then it works.

sorry i did´t have that with a LPRAR.

But did you clean the RMC

http://aix4admins.blogspot.de/2012/01/rmc-resource-monitoring-and-control-rmc.html

/usr/sbin/rsct/install/bin/recfgct

hope it helps! have a nice weekend

Hi All,

Below steps worked for me, Im able to migrate now, 

recfgct: deletes the RMC database, does a discovery, and recreates the RMC configuration
# /usr/sbin/rsct/install/bin/recfgct
(Wait several minutes)
# lssrc -a | grep rsct

(If you see IBM.DRM active, then you have probably resolved the issue)

- lsrsrc IBM.MCP   <--it shows HMCs via RMC

 

Thank you ALL...
