I'm relatively new to AS/400 System admin and now faced with a failed disk on my system(9406 - 520) V5R4M5.
When working with disk status (WRKDSKSTS) F11, the display screen appear as:
Unit ASP Type Status Compression
1 1 DPY UNPROT
2 1 DPY UNPROT
3 1 DPY UNPROT
4 1 DPY FAILED
Working with SST also display error on this disk. Technical support is provided by our external service provided.
Any technical advice will really help.
