5-32 Installing and Using Utilities
SCSI Status while IO Module is Starting or being Stopped
While an IO module is starting or being stopped, the status of SCSI adapters, SCSI bus, SCSI
enclosure, SCSI slots, and mirror disks temporarily indicates an undefined status. Once the module
is started or stopped, the status will return to normal.
Status of SCSI Slots and Mirrored Disks at High Load
When the system load is high, the status of SCSI slots and mirror disks may not be obtained, and
incorrect status may be displayed temporarily.
Event of "ESM HAS Storage Service" when Starting the Server for the First Time
After installing the server and when it is started for the first time or when it is started for the first
time after the system is reset up, an event that SCSI-related status has changed is registered.
However, the previous status in the message shows an undefined value.
Event 401 and 402 of "ESM HAS Storage Service"
An event "Status of SCSI Slot (ID:41/n) has changed from Empty to Empty" may be registered to
the event log because, internally, there are two types of the status "Empty" which indicates that a
disk is not mounted. For example, when no disk is mounted in both Slot 1 and Slot 4, "Empty" is
simply informational. Slot 1 also indicates "Empty" when a disk that no volume is created is in Slot
4. However, if a simple volume is created on the disk in Slot 4, the status "Empty" of Slot 1 is
handled as a warning in order to maintain redundancy. In such a case, check the status of volume
creation and configure mirror volumes.
SCSI Slot Indication when a Disk Fails
When a disk which has failed before is mounted, the SCSI slot status becomes "Broken." The status
changes from "Broken" when a mirror volume is created on the disk or any mirror volume is
resynchronized.
