Install a ES30 Diskshelf to a DD640

Generic:

We have bought an extra disc shelf (2nd one) to our DD640 full with 1TB disc . To be able to backup growing computer 1 and 0.

Installation:

Hardware

Software

Now we are using 5.4 and its license based for an extra shelf. thats is covered in other documents. There are two documents that do cover some docu50985 and docu50305. But the thing in DD640 is that it has the a limit of connecting shelfs as bobt@dd typed below.

Add license (i did that in GUI) system settings/license than add license

SSH to the DD640 and run commands (show for confirmations and others for do stuff)

> storage add enclosure

> storage show all

> filesys expand

> storage show all

> alerts show current

Thx for help on forum and support - Mail and Chat from EMC this was done without any problem.

thx Pontus Ankarbåge, Borlänge kommun

btw (verdana-font should be youre default font according to EMC type if not using META )

Docs do cover this subject - follow guidelines and you can't go wrong.

The documents are pretty straight forward. Make sure that you are not exceeding the maximum raw storage of the system and that your DD640 has 20Gb of memory. A DD640 will take only (2) 15 TB enclosures.

We do recommend powering off the system to add the enclosure. Power on the system once the enclosure is cabled and once the system is booted, add the enclosure to the volume. Then expand the filesystem.

Hi bobt, With "power off the system" for you mean the Data Domain itself (the "head") or the DD including all shelves ? Thanks ! --josb

The head at a minimum.

Personally, I would shut down the head and the enclosures, cable everything up, power on the enclosures, wait for all the external disks to spin up, then power on the head. It may take a bit more time but it will make sure that everything gets initialized properly.

Don't forget to run (assuming your DDOS is not ancient);

  • enclosure show topology
    • This will ensure you cabled SAS correctly and all paths are seen, this will display the SAS HBA in the controller and ">" illustrates a "cable" and then the 2.A.H: 2.A.E would signify the ES30 LCC controller card on the "A" side of enclosure 2. (H=host, E=expansion ports).
    • You should have 2 paths to each shelf - the A side and the B side for a DD640.
    • Each side of each shelf should not be cabled to the same SAS HBA - for redundancy.
    • Enclosure 1 is always the DD head (server), your shelves will be 2 and 3.

  • disk show state
    • This will show you the new disks as unknown before you add the shelf and then available once the shelf is added.
    • Take a look at this, it's pretty handy.
    • Obviously they need to all be available to be able to expand the filesystem.
    • There is a "key" shown below this command.

Regards,

Jonathan
