DFSMShsm CANNOT BE STARTED AS HOST=hostid, HOSTMODE=mode, REASON=retcode

Explanation

An attempt has been made to start DFSMShsm, with startup parameters HOST=hostid and HOSTMODE=mode. The retcode has the following meanings:

Retcode
Meaning
1
Another DFSMShsm, for an earlier release, has already started in this z/OS® image.
4
Another DFSMShsm has already been started as HOST=hostid in this HSMplex.
8
HOSTMODE is MAIN, and another DFSMShsm host is currently active in the z/OS image with HOSTMODE=MAIN.
12
The data set name of one or more control data sets in the startup procedure for HOST=hostid is not the same as that used for already started DFSMShsm host(s).
16
HOSTMODE is AUX, and the attempted method of CDS serialization does not comply with the following:
  • CDSSHR not specified, CDSQ=YES, and MCDS index on a DASD VOLUME defined as shared
  • CDSSHR=YES, CDSQ=YES
  • CDSSHR=RLS
20
DFSMShsm support for JES3 is disabled for a host started with HOSTMODE=AUX.
24
In a MASH environment a DFSMShsm host cannot be started when an active DFSMShsm host is performing CDS backup on the same LPAR.

System action

DFSMShsm startup ends. Existing DFSMShsm hosts continue.

Programmer response

Retcode
Action
1
If you want to run multiple DFSMShsm hosts in this image, shut down the earlier version.
4
Choose another value for HOST= that does not appear in the list of hosts identified by the command QUERY IMAGE, executed for each z/OS image in this HSMplex.
8
Review your intent for this second host and update the HOSTMODE, if applicable.
12
Update the startup procedure to correct whichever data set names are incorrect.
16
Update the startup procedure to correct the keyword values for CDS serialization.
20
The use of JES3 for an AUX host is not supported.
24
Wait for CDS backup to complete on the active DFSMShsm host, then attempt to start the indicated DFSMShsm host again.
