IST2219I

Explanation
 This message is issued during the activation of
a Multipath Channel (MPC) group because VTAM® could
not allocate at least one read device and one write device.   
 In
the message text: resource
The name of the TRLE or MPC subarea line that defines the MPC
 group. 

 VTAM also
issues this message as part of a message group in response to the
following:   A DISPLAY ID command for an MPC line or a transport resource list
entry (TRLE).  
A DISPLAY TRL command for an active TRL entry.   

 See  IST1221I for a description
of those displays.

System action
 Activation of the MPC group is suspended until
either the minimum required  number of devices comes online or the
MPC group is deactivated.  In the former  case, message IST2220I is
issued to signal that activation of the MPC  group has resumed.

Operator response
 Issue the D NET,ID=resource,E
command.  If message IST2219I does not appear in the display  output,
no further response is needed.  Otherwise, review all of the IST1221I
messages that contained in the display that have the chtyp value WRITE or READ.
 For each chtyp value that lacks a subchannel with
the system_state value ONLINE,
make at least one of  those subchannels in the offline system state
available. See IST1221I for more information
about the chtyp value.
 Issue the MVS™ VARY ONLINE command to make a
subchannel available.  If the  result indicates that the channel is
already online, then ensure that a valid  path to the connecting host
exists.    
 When the minimum required number of subchannels
is available, VTAM  automatically
allocates the devices and resumes activation of the MPC group.

System programmer response
 If you do not want automatic recovery
of MPC group activations, modify the MPCACT start option     to a
value of NOWAIT to enable you to try the activation of MPC groups
again manually; this     message will no longer appear.

User response
 Not applicable.

Problem determination
