Symptoms

I denne situation kørte Unity-systemet OE 5.2, og alle NL-SAS-drev var til stede i systemet.

Når du forsøger at oprette en pulje fra Unisphere, er kun RAID 6 tilgængelig (RAID 5 og RAID 10 er ikke tilgængelige).

Cause

Unity-systemet fungerer efter design.

I Dell Unity OE version 4.2 og nyere er en dynamisk pulje den eneste puljetype, der kan oprettes i Unisphere for et rent flash-system. Dette gælder også for hybridsystemer, der kører OE version 5.2 og nyere. Oprettelse af en traditionel pulje kræver, at du bruger Unisphere CLI eller REST API. Når du opretter en dynamisk pulje med NL-SAS-drev, er kun RAID 6 tilladt, når du bruger Unisphere.

Resolution

En traditionel pulje kan oprettes fra CLI ved hjælp af nedenstående kommandoer 
1) uemcli /stor/config/profile -traditional -configurable show    <- Shows the profiles available in the system

ID = tprofile_2
Type = Traditional
Description = SAS Flash RAID5 (8+1)
Drive type = SAS Flash
RAID level = 5
Maximum capacity = 18510768046080 (16.8T)
Stripe length = 9
Disk group = dg_26
Maximum drives to configure = 45
Maximum capacity to configure = 14834210439168 (13.4T)
  
2) uemcli /stor/config/dg show        <- Shows the Disk Groups available in the system 

ID = dg_26
Drive type = SAS Flash 3
FAST Cache = no
Drive size = 393846128640 (366.7G)
Vendor size = 400.0G
Rotational speed = 0 rpm
Number of drives = 47
Unconfigured drives = 47
Capacity = 18510768046080 (16.8T)
Recommended number of spares = 0
  
3) uemcli -d <IP Address> -u Local/admin -p <Password> /stor/config/pool create -name <Pool Name> -diskGroup dg_26 -drivesNumber 45 -storProfile tprofile_2 -type traditional           <- Command to create a traditional Pool (we use 45 of the 47 drives to leave 2 for spares)

Note: This command is run from a workstation with Unity uemcli installed.
Alternately the command can be run directly on the SP via an SSH connection:

uemcli -u Local/admin -p <Password> /stor/config/pool create -name <Pool Name> -diskGroup dg_26 -drivesNumber 45 -storProfile tprofile_2 -type traditional
