Are these windows clients? Is the dirmc (directory management class) pointed to disk or tape?
You may have windows clients queueing up to write their directories to tape. [RC] From: Keith Arbogast <warbo...@indiana.edu> To: ADSM-L@VM.MARIST.EDU Date: 04/30/2010 08:09 AM Subject: [ADSM-L] mediawait during backup to disk Sent by: "ADSM: Dist Stor Manager" <ADSM-L@VM.MARIST.EDU> What does it mean when a node incurs mediawait during a backup to disk? The disk pool was not full, or even close to the Hi Mig trigger. The mediawait condition is reported by TSMManager, not the Activity Log, but the node record does show roughly 50 % pct mediawait . Several clients showed this condition in TSMManager and the Pct Mediawait field, and all during the same period of the night. All tape drives would have been busy during this time, writing offsite backups of disk pools at our other data center.
