METHOD AND SYSTEM FOR REMOTELY CONTROLLING A STORAGE SHELF OF A STORAGE SYSTEM

摘要

System and method for remotely performing a power cycle operation for a storage shelf of a storage server using a control path independent of a data path used for processing I/O requests is provided. The storage server maintains a data structure for storing information regarding a state of a plurality of power latches that are used to control power for the storage shelf having an alternate control path module for receiving control commands via the control path. Depending on the state of the plurality of power latches, the storage server sends one or more commands to the alternate control path module to turn off power to the storage shelf during a power cycle operation. When the power shelf is powered off, the storage server waits for a certain duration and then sends one or more power on commands to the alternate control path module to power on the storage shelf.

主权项

1. A machine implemented method, comprising:
receiving, at a storage server, state information of a plurality of power latches that are used to control power for a storage shelf; wherein the storage shelf includes an input/output (I/O) module for processing input/output (I/O) requests from the storage server; and an alternate control path module for receiving control commands via an alternate path independent of a data path used for processing the I/O requests; sending one or more power off commands from the storage server to the alternate control path module to power off the storage shelf when the state information indicates that a power latch is in an on state; determining that the storage shelf is powered off within a certain programmable threshold duration after receiving the one or more power off commands; and sending one or more power on commands from the storage server to the alternate control path module to power on the storage shelf, after the storage shelf is powered off.
