  • Page 57: Powering Down The Ip4700

    Installing an IP4700 Powering Down the IP4700 To turn off power: 1. Stop all I/O activity to the IP4700. Refer to Chapter 8 in the IP4700 Administrator’s Guide (069701169) for a description of the storage processor shutdown procedure. NOTE: Stopping the I/O allows the storage processor to destage cache data, and may take some time.
  • Page 58 CAUTION Never remove the fan pack and shut off the power supply to shut down an IP4700. Doing so effectively bypasses the SPS, and write cache data cannot be saved to the vault drives, which results in data loss. When that happens, volumes become inaccessible and the unsolicited event log displays an error message similar to: “Enclosure 0 Disk 5 0x90a (Can’t Assign - Cache...
