Notification
Risk classification
HIPER (High Impact and/or Pervasive)
Affected Domain
Transparent Cloud Tiering (TCT) on DS8900F and/or DS8880
Abstract
- Customers may experience multiple warmstarts and dual IML, when restoring or recalling data from TS7700
- Customers may encounter data loss restoring or recalling data from any type of Cloud storage.
Description
- Risk category: Loss of Access
When restoring or recalling data from TS7700, if the data set spans multiple PPRC (GM or MM) volumes on DS8900F/DS8880, the DS8000 will warmstart multiple times, leading to a dual-cluster Initial Microcode Load (IML). Access to the affected DS8000 will be lost until IML is completed.
Other cloud storage types are not affected. - Risk category: Loss of Data
Cloud migration over a degraded network connection, may expose a timing window where the object was not migrated, but the operation completed with good status.
Recommended Action
Mitigation:
None.
None.
Fix:
Install the appropriate fix bundle(s)
DS8880: R8.5 SP10.2 - 88.59.28.0 or newer
