Physical disk takes a long time to rebuild
- Issue:
- A physical disk is taking longer than expected to rebuild.
- Description:
- A physical disk takes longer to rebuild when under high I/O stress. There is only one rebuild I/O operation for every five host I/O operations.
- Corrective Action:
- If possible, reduce I/O stress on the physical disk or increase the value of rebuild rate controller parameter.
