1128 Power Supply Unit missing

Explanation

The power supply unit (PSU) is not seated in the enclosure, or no PSU is installed.

User response

  1. If no PSU is installed, install a PSU.
  2. If a PSU is installed, reseat the PSU in the enclosure.
Attention: On SAN Volume Controller 2145-DH8 or FlashSystem V9000 control enclosure AC2, if the error is displayed for the top power supply unit (PSU 2), to avoid losing state and data from the node use the satask startservice command to put the node into service state so that it no longer processes I/O. Then, you can remove and replace the top power supply unit (PSU 2). This precaution is due to a limitation in the power-supply configuration. After the service action is complete, run the satask stopservice command so that the node can rejoin the system.

This note does not apply to SAN Volume Controller 2145-DH8 or FlashSystem V9000 control enclosure AC2 manufactured on or after 1 April 2015, with battery backplane FRU part number 00RY001 and battery backplane voltage sense cable FRU part number 00RY335.

It also does not apply to any version of FlashSystem 900.
