Storage System Shutdown And Startup; Powering On Disk Enclosures - HP EVA P6000 User Manual

The transceiver dust caps protect the transceivers from contamination. Do not discard the dust
covers.
CAUTION:
whenever a transceiver or a fiber cable is disconnected. Remove the dust covers or dust caps from
transceivers or fiber cable connectors only when they are connected. Do not discard the dust covers.
To minimize the risk of contamination or damage, do the following:
Dust covers—Remove and set aside the dust covers and dust caps when installing an I/O
module, a transceiver or a cable. Install the dust covers when disconnecting a transceiver or
cable.
One of the many sources for cleaning equipment specifically designed for fiber optic connectors

Storage system shutdown and startup

You can shut down the array from HP P6000 Command View or from the array controller.
The shutdown process performs the following functions in the indicated order:
1. Flushes cache
2. Removes power from the controllers
3. Disables cache battery power
4. Removes power from the drive enclosures
5. Disconnects the system from HP P6000 Command View
NOTE: The storage system may take several minutes (up to 15) to complete the necessary cache
flush during controller shutdown when snapshots are being used. The delay may be particularly
long if multiple child snapshots are used, or if there has been a large amount of write activity to
the snapshot source virtual disk.

Powering on disk enclosures

IMPORTANT:
the servers, during their discovery, see the enclosure as an operational device. If you do not power
up the disk enclosures before powering up the controllers and servers, you will need to power
down the servers, ensure that the disk enclosures are powered up, and then power back up the
servers.
1. Apply power to each UPS.
2. Apply power to the disk enclosures by pressing and holding the power on/standby button on
the rear of the disk enclosures until the system power LED illuminates solid green.
The LED on the power on/standby button changes from amber to solid green, indicating that
the disk enclosure has transitioned from a standby state to fully powered.
3. Wait a few minutes for the disk enclosures to complete their startup routines.
CAUTION:
routine, the server might not properly discover the storage.
To avoid damage to the connectors, always install the dust covers or dust caps
Always power up disk enclosures before controllers and servers. This ensures that
If power is applied to the server before the disk enclosures complete their startup
