Adding new disks in the PS4100

You are very welcome.  Glad to be of service.

Don,

It was what we expected response.

thank you.

Hello,

I already bought the disc and need to do to expansion.

What is the procedure to increase my array, after entering the new disks in drawers?

Simply put discs in drawers that they will be included in the array member?

PS: You're asking to update the firmware. I do before or after entering the new disks?

Thank you.

Hello Sandro, 

 There's a special process on arrays like the 4100 that create multiple RAIDsets in the single chassis when you have upgrade drives that are larger than the original.  I assume they are the same speed correct?  If not then you can not mix speeds in the same chassis.  

My suggestion is opening a support case and they will work with you to correctly get the new larger drivers properly added to the member. 

Re: firmware.  Looking over this thread I don't see where I talked about firmware.  It's always best to run current firmware.   What firmware are you currently running? 

Regards, 

Don 

Hello,

it seems that is simple, then.

I'll put 12 discs the way you directed. (Partly, then one by one'll inserting completely).

When I enter the group manager, my MEMBER today appears disk 12-23 empty, will be allocated with these new discs.

Today the total capacity is 4.18TB with 12 disks.

After finishing the automatic storage process, this capacity will increase to 8.36TB about, right?

My storage:
-Storage Array Firmware V6.0.7 (R367725)
-RAID50 / (10) Disks 558.91GB / (2) Spares / 1KRPM
-Total Gross: 4.18TB
-Total Useful: 3.56TB

Regarding the firmware update, should I do after this process of adding disks, or before adding the disks?

I will continue using the two spares discs, or I'll have to set new 2 spares discs for this new set of disks?

Thank you.

Hello,

yes, they will be identical disks of the same capacity speed.

I understood that with the inclusion of more 12 identical disks I will not need to create a new set array.

I bought exactly the same amount that currently have.

Excuse me. I quoted the firmware because I was told that there is a process that when updated firmware, it will drill the array automatically.

Thank you.

Sorry in re-reading the thread I thought you got 1TB drives. 

 For better performance the 4100 creates RAIDset for each set of 12 drives.  So when you add in the other 12 the array will create a new RAIDset for them using the already defined RAID type. 

 So the process is easy.  Put the new drives in the slots but don't seat them fully in the slots.  Leave them out a 1/4 inch or so.  Once all the drives are staged, then you can seat them one at a time, one right after the next w/o pausing between them.   Once they are all fully seated the array will wait a minute or so then start to build the new RAIDset.   Once that's finished, the new space will be available to that array.  Then the data will be redistributed to the new set of drives. 

 Sorry I'm not sure what you mean by "drill the array"?    

 What firmware are you running now?   

Regards, 

Don 

Thanks you very much 

6 Weeks To Evolved Recovery

Hello, 

Re: Firmware update.  That's up to you, but you won't be able to do it afterwards until the RAID construction completes.  if you're taking an outage I would do the firmware upgrade first. 

re: 6.0.x.  This version stream no longer gets updates, so I would suggest you upgrade to at least the current 7.1.x firmware.   Which you can do in one step.  If you decide to go to 8.x, then you first have to install 7.x, restart, then you can install 8.x. 

re: Spares.  Spares in this case are global to the chassis.  The number of spares is determined by RAID type. 

Don

Hello,

perfect.

I believe I did.

After inserting the disc, the storage will automatically perform the process of RAIDset by adding new disks in the empty slot and the ability of my pool-01 storage appear more capable to use.

The spares will continue to be the two current.

Regarding the firmaware, I will download the version 7 and 8. And I performed the update in sequence, before adding the disks.

I am sure the work to be done?

Thank you.

2 Cent Traffic System Review www.youtube.com/watch
If you are looking for high quality PLR then I highly recommend 2 Cent Traffic System. Its actually 5 traffic packages for one low price and is provided by the Dr. Amit Pareek and the HQ Plr Store Team.
They have set the standard for amazing Video Training PLR in particular.

Hello, 

That sounds great.

Hello,

Now came the new hard disks!

As to complement.

When you say:

- Leave Them OUT A 1/4 inch or so.

- Once all the drives are staged, Then you can seat Them one at a time, one right after the next w / o pausing between Them.

I understood:

- Place almost entire inside, and a part outward;

- Will occur an automatic scanning process, that is, I hope a little after putting all of that position;

- Fit the rest of the disc is out;

- The docking sequence is to start on the right and go into place the other;

Sorry for the English translation.

Thank you.
