Symptom Possible causes Solution 5. Repeat this procedure for each server visible to each SDLT tape drive. At reboot, there are spurious critical FC port failures reported as notification alerts, usually on every port. Later, Info notification alerts for each FC host port are generated, indicating the FC ports are operating normally. This is expected behavior and does not indicate a problem. None After replacing drive 0 in a node, the system will not boot. A blank drive was installed in drive bay 0. If a blank drive is installed in drive bay 0, the system will not boot. To remedy this, switch the drive located in bay 0 with the drive located in bay 1. When oversubscription is enabled and you create enough cartridges in a storage pool to put your free storage capacity below the threshold, the pool may reach critical status. If you then disable oversubscription, your storage pool will remain in critical status and will not return to good status-even after reboot. When you disable oversubscription, the system does not monitor the storage pool's capacity, even to check that it is no longer at a critical level. The status will not change. Re-enable oversubscription, set the alert threshold so that the storage pool is within the capacity threshold, then wait for the pool to return to good (green) status. Disable oversubscription and the storage pool will maintain good status. Automigration/Replication Issues Although Automigration is configured and managed through the Automigration/Replication tab on Command View VLS, errors and events are reported through the usual notification alerts. See Notification Alerts. IMPORTANT: If a destination library is directly connected to the VLS (LOOP mode), and you disconnect the destination library to change its connection to be via a SAN (FABRIC mode), you will need to reboot the VLS in order for this change to work. If you do not reboot, the destination library will be marked as FAILED after you disconnect and reconnect it. NOTE: The "mirror_broken" state can occur when there is not enough room on the virtual tape to create the copy, there are no available slots to create the copy, the library cannot read the header of the physical tape, the library cannot determine that a tape without a header is blank, or the library cannot successfully write the header to the virtual tape.
