APC 15000 RAID manual Tier Mapping for Enclosures

3.2.2.7Status of Drive Enclosures

The SES command displays the failures reported by the enclosure (Figure 3–19),through the SCSI Enclosure Services (SES). It also provides a means to access SES specific functions such as disk, channel, and LUN. Drive failures are not displayed using the SES command; you must use the TIER command to view drive status.

Figure 3–19Displaying the Current Disk Enclosure Failures

If your enclosures provide redundant SES communication paths, the error is reported twice. In Figure 3–19,EncID is the Enclosure Logical Indentifier of the enclosure that reported the failure. The last four digits of the WWN are the last four digits of the enclosure’s serial number.

SES ON saves the SES state to the parameter blocks, and starts up the SES monitors.

SES OFF saves the SES state to the parameter blocks, and shuts down the SES monitors.

3.2.2.8Display SES Devices Information

SES SHOWDEVICES displays all the SES devices on all channels.

SES SHOWALL displays all configuration information for all the SES devices on all channels.

SES SHOW=<tier><channel> displays the configuration information and the status information returned from an SES Enclosure Status page for the SES device for the specified drive in the range of <1..120> and <ABCDEFGHPS>.

3.2.2.9Visual Indication of Drive

SES IDDISK=<tier><channel> provides a visual indication of the specified drive

(<1..120><ABCDEFGHPS>). The status LED of the drive blinks until the command SES ID=OFF is issued. The SES ID=OFF command restores the system to its original visual state.

3.2.2.10Visual Indication of Tier

SES IDTIER=<tier> provides a visual indication of the specified tier <1..125>. The status LED of the drives blinks until the command SES ID=OFF is issued, which restores the system to its original visual state.

3.2.2.11Visual Indication of Channel

SES IDCHANNEL=<channel> provides a visual indication of the specified channel

<ABCDEFGHPS>. The status LED of the drives blinks until the command SES ID=OFF is issued, which restores the system to its original visual state.

3.2.3Tier Mapping for Enclosures

The controller supports various drive enclosures. When the system is first configured, it is necessary to select a tier mapping mode so that the position of the tiers in the system are changed to conform with the layout of your drive enclosures. The tier mapping information also allows the controller to properly light the enclosure fault LEDs.
