SCSI Hot Swap Manager
This task was known as ″SCSI Device Identification and Removal″or ″Identify and
Remove Resources″in previous releases. This task allows the user to identify, add,
remove, and replace a SCSI device in a system unit that uses a SCSI Enclosure
Services (SES) device. The following functions are available:
vList the SES Devices
vIdentify a Device Attached to an SES Device
vAttach a Device to an SES Device
vReplace/Remove a Device Attached to an SES Device
vConfigure Added/Replaced Devices
The List the SES Devices function lists all the SCSI hot-swap slots and their contents.
Status information about each slot is also available. The status information available
includes the slot number, device name, whether the slot is populated and configured,
and location.
The Identify a Device Attached to an SES Device function is used to help identify the
location of a device attached to a SES device. This function lists all the slots that
support hot swap that are occupied or empty. When a slot is selected for identification,
the visual indicator for the slot is set to the Identify state.
The Attach a Device to an SES Device function lists all empty hot-swap slots that are
available for the insertion of a new device. After a slot is selected, the power is
removed. If available, the visual indicator for the selected slot is set to the Remove
state. After the device is added, the visual indicator for the selected slot is set to the
Normal state, and power is restored.
The Replace/Remove a Device Attached to an SES Device function lists all
populated hot-swap slots that are available for removal or replacement of the devices.
After a slot is selected, the device populating that slot is Unconfigured; then the power
is removed from that slot. If the Unconfigure operation fails, it is possible that the device
is in use by another application. In this case, the customer or system administrator must
be notified to quiesce the device. If the Unconfigure operation is successful, the visual
indicator for the selected slot is set to the Remove state. After the device is removed or
replaced, the visual indicator, if available for the selected slot, is set to the Normal state,
and power is restored.
Note: Be sure that no other host is using the device before you remove it.
