A virtual machine gets stuck in migrating status

Edit online

Use this information if your Red Hat® Enterprise Linux® 6.5 server virtual machine with vSCSI storage connectivity gets stuck in Migrating status as reported on the Hardware Management Console (HMC).

Investigation

On the HMC, look for

Migrating -
Running

in the system's status:

hscroot@<hmc>:~> lssyscfg -m <host> -r lpar -F name,
     lpar_id,lpar_env,curr_lpar_proc_compat_mode,state,rmc_state
     my_system-0aa710ab-00000003,3,aixlinux,POWER7,Migrating - Running,
     active

On PowerVC, you might see periodic messages in the console that are related to this virtual machine and its state. However, the migration does not complete.

Explanation

This issue is caused by a vSCSI RHEL 6.5 bug. For details, see the LTC Bugzilla page. For details about recovering from a failed migration by using the hardware management console (HMC), see Recovering from a failed migration.

Resolution

Use a deployed image from RHEL 6.6 or from a different release stream that does not have the issue. The problem is intermittent and does not occur in every RHEL 6.5 installation. It also might be possible to obtain a z-stream update or hot fix patch for this problem from Red Hat.
