Troubleshooting
Problem
A Tivoli Storage Manager for Space Management client is installed on AIX. Files are migrated migrated from a JFS2 file system using the HSM client. The AIX "cp" command fails to copy a migrated file with the above error
Symptom
The following error is reported when trying to copy a file using the "cp" command:
There is no process to read data written to a pipe
Cause
File system is not managed by HSM anymore
Diagnosing The Problem
Verify that the file system from which files were migrated is still managed by HSM. Run the following command :
dsmmigfs query
In this case, the file system was previously managed by HSM and files were migrated to a Tivoli Storage Manager. The dsmmigfs query command would show the file system is longer managed by HSM but still contains files that were migrated.
Resolving The Problem
Reconfigure the file system to be managed by HSM using the dsmmigfs add command. For example:
dsmmigfs add /filesystem_name
