9.3 Hot System Replacement

The Expansion File Unit Type-2 is not powerd on/off by only the main line switch, but it linked to power on/off of the GP7000F main cabinet. Note that this file unit does not power on if the main line switch is OFF, even if the GP7000F main cabinet is powered on. Keep the main line switch set to ON for regular use.

Be sure to set the RCI configuration, which is detailed in Chapter13 , must be set properly when installing an Expansion File Unit Type-2.

The cabinet has 2 pair of SCSI IN/OUT connectors on it. When the cabinet is configured without expansion (optional) drive bays, a SCSI cable must be connected to the standard SCSI IN connector. Be sure to install an UltraSCSI differential terminator plug to the SCSI OUT connector.

CAUTION

Do not set the AC main line switch to OFF, nor disconnect the power cable or RCI cable while the GP7000F main cabinet is powered on, unless absolutely necessary. Otherwise, the data in the disk units may be destroyed.

9.3 Hot System Replacement

Disk unit The SCA-II connector is used as the disk unit connector to enable hot system replacement of a faulty disk unit. The availability is improved by combining this feature with the disk mirroring features. Two LEDs (ACTIVE and FAULT) are installed per disk unit to indicate the disk unit status. These LEDs operate as described below.

To hot-swap a disk unit, you need to use the software tool which is provided in "Basic Software Extension" or "Enhanced Support Facility". Please refer to user’s guide of "Basic Software Extension" or "Enhanced Support Facility"for more information. The FAULT LED lights up according to the procedures described in the user’s guide to identify the failed disk unit. If the FAULT LED does not lights up even if you follows the procedures described in the user’s guide, hot-swapping is not possible. In this case, power-off the entire system, then replace the disk unit. When adding a new disk unit while the system is running, use the software tool, as well.

Power When the power supply units are configured redundantly, it can be hot-swapped. Each power supply unit has a POWER LED on it, and it lights steadily while the corresponding power supply is working. When the POWER LED doesn’t light, it indicates that the power is turned off or the power unit has failed. Hot replacement of the power supply unit is possible only while the corresponding POWER LED is off.

Use a software tool, which is provided in "Basic Software Extension" or "Enhanced Support

Facility", to how-swap a power supply unit. Please refer to user’s guide of "Basic Software

Extension" or "Enhanced Support Facility" for more information.
