Unity how can you tell what a RAID Group is made up of

Glenn

Thanks unfortunately as the system grows and it will that’s not a great way for a customer to figure it out.

When you first create a Pool and select a tier - the Capacity Tier (NL-SAS) disks will default to a 6+2 R6. After the have created the Pool you can see which disks are in which tiers so you should have a idea of the configuration of the disks = go to Pool Properties and look in the FASY VP tab - this should show the tiers and the Raid Type and the number of disks. But the only way to determine how the disks are arranged would be to remember what you selected when you were creating the Pool. For example, if you selected SAS R5 you could select "Other" for the number of disks - 4+1, or 8+1 or 12+1. Once that is selected, I don't see any other way to determine how it was set up originally in the GUI, but there is a UEMCLI command that will show the Pool configuration - the "Stripe Length" is the number of disks in each private riad group within that tier. So 15 disks, R5, Stripe=5 means it's set for 4+1.

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/tier -pool pool_1 show -detail

2: Name                = Performance

Drives                   = 15 x 600.0G SAS

Drive type             = SAS

RAID level            = 5

Stripe length        = 5

Total space          = 7087501344768 (6.4T)

Current allocation = 0

Remaining space = 7087501344768 (6.4T)

uemcli can provide this info in detail.  Recently i wrote a script that can show details (main input from uemcli) for a solution engineer. Sample output is :

Above was derived from pool, tier output and disk outputs.

For Unisphere GUI, like glen said, feature can be requested

I just discovered that you can get the raid group information from a Service command.

If you run the following command it creates a file that you can then download using WinSCP. Once downloaded you can view the file in a browser.

/EMC/backend/service/configuration_history/20160824_161601_APM00161406789_EMC-UEM-Telemetry.html

The file is stored in the path listed after the command - I then logged into the array using WinSCP (using the Service user and service password) and went to the location above and downloaded the file and opened with Chrome - this looks very similar to the USM tool when opening the arrayconfig.xlm file from the VNX. There is a tab called Storage/Raid Groups - this shows the internal raid groups with the disks in each raid group.

The other files (.tar.gz) contain the same information but in separate CSV files (ie., 20160707_000117_APM00161406789_raidGroup.csv).

These files (Telemetry) are also in the Service Data file. Open the Service data file in ZIP, the look in the SP that is the Primary SP (for example SPA) and follow the path to:

\spa\EMC\backend\service\configuration_history\

that is great find, Glen. This is same as the Unisphere -> Service -> Service Task -> Save Configuration.

Very interesting traveling but will try later

Thanks
