One or more connections to a partition have been lost.

1. Is the HMC reporting any other reference codes that indicate a loss of communication with other partitions?
   • No: Choose from the following:
     • If the partition is running i5/OS^®, go to step 2.
     • If the partition is running AIX^® or Linux^®, go to step 3.
   • Yes: Resolve the first of these reference codes. This ends the procedure.

2. Open a 5250 console to the partition. There should be seven jobs running:
   • 4 of these jobs start with QCST*
   • 2 of these jobs start with QYUS*
   • 1 of these jobs start with QSVRM*
   Are all seven of these jobs running?
   • Yes: Go to step 4.
   • No: End all of those jobs that are still running and then issue the following command:

     SBMJOB CMD(CALL PGM(QSYS/QCSTCTSRCD)) JOBD(QSYS/QCSTSRCD) PRTDEV(*JOBD) OUTQ(*JOBD)
      USER(*JOBD) PRTTXT(*JOBD) RTGDTA(RUNPTY50)

     This ends the procedure.

3. Perform the following:
   1. Open a virtual terminal console to the partition.

   2. Verify that Service Resource Manager (SRM) is running properly by entering the following command:

      lssrc -a |grep ServiceRM

      If the state given for SRM is "inactive" then SRM is not running and needs to be restarted. If the state given is "active", then go to step 4.

4. Has the partition logged any LAN adapter or other LAN reference codes?
   • No: Work with the customer to find and resolve any network problems between the HMC and the partition. This ends the procedure.
   • Yes: Resolve these reference codes. This ends the procedure.
