Hi
We are looking at adding 4 additional drive enclosures to our 7400 (4 node). We currently have 10 additional enclosures.
I'm just looking for some guidance on the best way to do this:
We will add 2 at the top of the enclosure, and 2 at the bottom.
Looking at the StoreServ installation guide, it looks pretty straightforward, except for the cabling:
http://h20628.www2.hp.com/km-ext/kmcsdi ... 6625-9.pdfTo add expansion drive enclosure:
1. Install the expansion drive enclosure. See “Installing Enclosures ” (page 25).
a. Install the disk drives. See “Installing a Disk Drive” (page 28).
b. Cable the enclosures to each other by using SAS cables. See “Cabling the Storage
System” (page 38).
NOTE: For the drive enclosures, verify that the activity LED is functional (all four LEDs will
be lit solid green), and the LED at the front of the enclosure has a number.
2. Install the 580 W PCMs into the drive enclosure.
3. Install the power cables to the PCMs and press the power switch to ON.
4. After you have completed the physical installation of the enclosures and disk drives, cable the
drive enclosure to the controller nodes.
5. Verify the upgrade is successful.
I understand 1a, my question is around the cabling.
As Node 1 is currently connected to the bottom 2 shelves, would you remove these 2 cables from the bottom shelves, add the SAS cables between the old and new shelves, power the new shelves on, and then reconnect the controller cables to the new bottom 2 shelves?
Then do the same with the top shelves?
