Managing Storage Managers

Storage Manager Status
The Status column in the Storage Managers list reports the status of the Storage Managers logged by the
System Director. (The Status line in the Details panel reports the same information.) If the Storage Manager
maintains a working status, the ISIS Management Console lists no entries in the Status field. When a problem arises,
or when the status of the Storage Manager changes, the ISIS Management Console updates the Storage Managers
display.
The following table summarizes the Storage Manager status messages, in alphabetical order.
Status Description
Data conversion mode A fully populated ISIS 2000 system is running a one-time data conversion redistribution.
This mode applies only to ISIS v4.5 on ISIS 2000, and is required to upgrade a fully
populated ISIS 2000 from v4.5).
Demonstration mode A system is configured to run in demonstration mode with limited ability. Demonstration
mode runs on non-approved hardware (such as a laptop).
Disk Failure The hard disk error threshold for a disk has been exceeded and the Storage Manager has
taken the disk offline. The default threshold is 25 hard errors.
• For the ISIS | 7500, a Storage Manager or disk showing this status should be removed
from the Storage Group, triggering a redistribution. Once the redistribution is complete,
the Storage Manager on the ISIS | 7500 can then be removed from the file system, and
physically removed from the Engine.
• For the ISIS | 5500 and ISIS | 2500, the disk should be removed, not the entire Storage
Manager. The disks should be left physically in the Engine as the disk participates in the
redistribution.
Disk full One or more Storage Managers in a Storage Group has reached its full capacity. Even if
some of the Storage Managers still have available space, the Storage Group is considered full
as soon as one Storage Manager is filled. As data is written and deleted, some Storage
Managers are filled before others. During redistribution, the data is redistributed evenly
among the Storage Managers.
Disk Performance Degraded Disk Performance Degraded: There are two parameters that can trigger this status.
• A disk has logged a Long Command Time. The ISIS system periodically clears this log.
The Long Command Time counter is also cleared during a reboot.
• Once a disk reaches 75% of its hard error threshold, it triggers disk performance degrade.
This status is reset only by rebooting the Engine.
If an ISIS | 7500 Storage Manager is reporting this status, remove the ISB from the
Storage Group, triggering a redistribution.
Drive controller error (ISIS | 5500) The drive controller has reported an error.
Foreign disk A drive with an existing RAID signature has been inserted into a system and cannot be used
as a spare or as part of a RAID configuration until the signature is cleared. To clear the
foreign configuration, see the Avid ISIS Setup Guide. When you click “Format Foreign
Disks” the Status is cleared.
Initializing The ISIS | 5500 and ISIS | 2500 RAID set is being initialized. This could take several hours
to several days. You can use the Engine while the RAID set is initializing.
Install failed - Phase # A message displays if the ISIS | 7500 ISB fails during the three phases of the upgrade or
during the two phases of the ISIS | 2500 upgrade.
