Troubleshooting
Problem
Customer had not initiated any new migrate to cloud commands for over 3 months.
After many days of not migrating to the cloud, the first migrate data set command failed with the following errors:
ARC1581I UNEXPECTED HTTP STATUS 401 DURING A GET FOR URI
ARC1581I (CONT.) https:/cloud.name.com/auth/v1.0 ERRTEXT HTTP/1.1 401
ARC1581I (CONT.) Unauthorized
ARC1001I user.data.set.name MIGRATE FAILED, RC=0008, REAS=0018
ARC1208I ERROR ALLOCATING MIGRATION COPY
Cause
The unauthorized failure is being returned from the DS8000 and Cloud interface.
Environment
DFSMShsm
DS8K Cloud
TS7700
DS8000 Cloud
Resolving The Problem
The best way to confirm whether or not there is an error with the credentials for the Cloud:
- Issue the following HSM SETSYS command:
- HSEND SETSYS CLOUD(NAME(cloudname) CCREDS)
- Respond to the message asking for the credentials. When providing credentials, place a single quote around the entire string of credentials.
- NOTE: No messages are returned to the user if the command was successful.
NEXT:
- Try the HMIGRATE of a data set to the cloud again and it should succeed.
- If it does not, there could be another issue between the z/OS host and the DS8000 cloud. Verify the credentials on the hardware side to confirm they match what is being used on the z/OS host.
