Adding new drives enclosures to the EVA8000

[Nahimm]

Gentles, thank you very much for explanation!!!

How I understand, 4 additional shelfs can be connected using following way:

- shutdown EVA
- connect all the shelves
- install all drives
- power up EVA
- verify each shelf has proper ID number
- adding new disks into necessary disks groups

...and all system should work correctly?

What XCS version is the EVA at?


You don't necessarily need to shut down the EVA to do the upgrade.

> What XCS version is the EVA at?
XCS v6.220

Is this method correct if we shutdown EVA?

If all shelves are filled in differently... Like that for instance:
1 shelve - 8 disks
2 shelve - 14 disks
3 shelve - 12 disks
4 shelve - 9 disks
5 shelve - 13 disks
6 shelve - 14 disks
and we need to fill in all shelves fully and add two more fully filled shelves (+2 shalves/28 disks).
What do we do in this case?
What principle should we follow when we need to add new disks in disks groups?

Thanks.

Well, here is how you might proceed...

1. Backup your data, full backup
2. Check Command View EVA for any errors, oddities and the like. Fix issues.

3. Install new shelves into EVA cabinet
4. Install new drives into these shelves and connect power cables. NOT THE COPPER I/O CABLES.
5. Populate the rest of the disk shelves with the extra drives... 1 disk at a time... waiting about 90 seconds in between each drive. Check Command View to make sure the disk is recognized and properly placed in the ungrouped disks catagory.
6. Once all the disks are in, make sure once again in Command View that everything is in "good" condition.
7. Proceed to add the new shelves, one at a time to the back end switches. Connect 1 I/O module, wait for it to appear in Command View and possibly update it's EMU code, than add the second I/O module.
8. Once everything is installed, Check Command View once again, make sure all is good.. and add disks to a group.


There is a document somewhere that tells you where to plug in the new shelves. I do not have it handy at the moment.

>>> I always to the slower more cautious route. I would do the following...
- verify the EVA health; make sure no levelling is in progress. Make sure no devices have a caution.
- reboot the server thatâ s running Command View
- shutdown the EVA
- connect the 4 new disk enclosures correctly including I/O A, I/O B and shelf ID cable.
- install one disk drive in bay 1 of 14 of each disk enclosure.
- power on the EVA
- verify each disk enclosure received its proper shelf ID number by looking at the back
- start Command View, verify there is no Unmapped Hardware; no cautions on any devices, there are now 4 disks in the ungrouped disk group
- shutdown the EVA
- install all the remaining drives fill in the left columns first up to bay 11
- add the last drive to shelf 1 bay 12
- result...
1 shelve - 8 disks - 12
2 shelve - 14 disks - 14
3 shelve - 12 disks - 12
4 shelve - 9 disks - 11
5 shelve - 13 disks - 13
6 shelve - 14 disks - 14
7 shelve - 11 disks
8 shelve - 11 disks
9 shelve - 11 disks
10 shelve - 11 disks

- Run the EVA disk drive firmware bundle version May 2009 before adding the disk to the disk group.


What principle should we follow when we need to add new disks in disks groups?
>>> you have not provided disk group nor disk drive information
- If you only have one disk group add all the drives at onceâ ¦
- i.e. DG 1 â (8x15) = 120 disks Grand Total 120 disks
- Verify levelling starts
If you have two or more disk groups, then add enough disks to each group so the disk group ends up with a multiple of 8 disk drives.
i.e. DG 1 â (8x8) = 64 disks, DG 2 â (8x7) = 56 disks Grant Total 120 disks
- Verify levelling starts

According to the latest HP documentation, it states that to add the connector cable and then the shelves the system must be shut down. When you talk about adding the shelves to a running EVA I assume you men simply connecting to the bus cable that is already connected to the EVA. Have any of you installed the bus cable while the EVA is up and running?
