Managing Storage Managers

Install needed This message displays if the ISIS | 7500 or ISIS | 2500 Storage Manager (Engine Controller

in ISIS | 2500) is not at the same version of the ISIS System Director software. Select all the

storage Managers and click Upgrade.

Install needed - No Connection (ISIS | 7500) This a normal one-time message displayed only during the upgrade from v4.0

and earlier to v4.0.1 and later.

Invalid number of drives The Storage Manager has determined it doesn't have enough drives to run in the bound

operating mode. In this mode the Storage Manager only communicates with the System

Director, no clients are allowed to connect, and the Storage Manager is not functional in the

Storage Group.

Once the Administrator has addressed the issue in the Storage Manager, the Storage Manager

must be restarted via the Storage Manager agent.

Invalid spare drive A replacement drive installed to become the new spare is not qualified as an acceptable spare

drive for this Engine. Obtain another replacement drive. When a valid replacement drive is

installed, it becomes the new spare and the status is cleared.

Memory Error The Storage Manager runs a memory test when it starts or restarts reports any errors; this

status is persistent. Replace the Storage Manager as soon as possible.

Metadata error (ISIS | 7500) The Storage Manager experienced an error loading metadata from the disk or

writing new metadata to the disk (if mirrored in the ISIS | 7500, the data on the mirrored

Storage Manager is still available and no actual data loss occurs); this indicates that the

Storage Manager should be replaced.

Reboot the Storage Manager with this status. If “Metadata Error” status exists after a reboot,

replace the Storage Manager. If the Metadata Error status clears after a reboot, then no

further action is required.

Missing spare drive (ISIS | 5500 and ISIS | 2500) A rebuild automatically occurs on drive failure by using a spare

disk in the Engine. When the spare has been used to replace a failed disk, this warning

message is displayed in the Management Console. Obtain a replacement drive for the failed

drive. When the replacement drive is installed, it becomes the new spare and the status is

cleared. There is one spare drive in each ISIS | 5500 Engine and two spare drives in each

ISIS | 2500 Engine.

Network degraded The IP interfaces on the Storage Manager have failed or the Storage Manager experiences at

least a 10% error rate (usually due to lost packets), indicating a network communication

problem.

Although the Storage Manager is reporting and detecting the errors, it is usually not the

Storage Manager itself that is the problem. Seating issues, slot issues, midplane problems,

switch problems, stacking issues, or anything that contributes to bad data getting to the

Storage Manager can cause this status. See the tech note “How to troubleshoot Network

Degraded” for further details on how to handle this status.

Offline (ISIS | 7500) The Storage Manager has been taken offline. It is good practice to take a

Storage Manager offline before reseating or removing it.

Rectifying Files The Storage Manager is cleaning up deleted files and verifying existing files. This occurs

every time the Storage Manager restarts and every 10 days thereafter, and also when

manually initiated. Each Storage Manager staggers their process so that they do not run

simultaneously.

Redistribution details available A problem with redistribution occurred. Open the Agent page for the Storage Manager to see

the details.
