PowerStore Alerts: Drive Evict State

Summary: PowerStoreOS 4.3.0 and above introduce a new feature to allow automatic eviction or manual eviction of drives. Evicting a drive allows to proactively copy the data from the evicted drive to a newly added drive. There should be minimal impact to the customer during this process. The eviction process allows for a faster recovery from a drive that is about to fail as the system can endure another drive failure (unlike with standard drive rebuild where we cannot lose another drive). PowerStoreOS automatically attempts to evict drives that reach 95% wear level to allow for faster recovery. The eviction process can only be performed on a single drive at a time, and it can be cancelled before the new drive is added and eviction (data copy) is actually started. ...

Resolution

Cause
These alerts indicate the eviction process was triggered (either by user or by the system) but cannot start due to an issue. The issue is described in the PAUSE_REASON.

Solution
Review the associated reason below and fix the underlying issue. Once the issue is resolved, the drive eviction process should automatically start.

PAUSE_REASON Action
evict_pending_no_dst_device After setting a drive to evict, a new drive needs to be added for the eviction process to start, add a new drive (same size or larger) on an empty slot on the same enclosure so the eviction process can start.

The reason can also indicate that an existing drive (that is not the source drive) has failed and rebuild completed. Replace the faulty drive. eviction process will resume once drive is replaced.
evict_pending_new_device_in_wrong_slot A drive was added in the wrong slot, possible reasons:
  • There is room for an additional drive in the DPE but a new drive was added to a DAE.
  • If the drive to evict is located on a DAE, the new drive cannot be located on the DPE. it must also be located on a DAE.
