Dell Unity: Så här expanderar du en Unity-pool med hjälp av CLI
Summary: I den här artikeln beskrivs hur du använder Unity Enterprise Management CLI (UEMCLI) för att utöka en befintlig Dell Unity-lagringspool genom att lägga till en ny diskgrupp. I exemplet visas kommandot poolutökning, inklusive de parametrar som krävs, till exempel pool-ID, diskgrupps-ID, antal enheter och lagringsprofil. Proceduren kan användas för att öka tillgänglig kapacitet samtidigt som poolens önskade lagringsnivåindelning och prestandaegenskaper bibehålls. ...

Instructions
1. Kontrollera status för poolen och få information om enheten och RAID-gruppen:
uemcli /stor/config/pool -name <pool_name> show -detail
Example:
14:11:25 service@xyz spb:~/user> uemcli /stor/config/pool -name XYZ123 show -detail
1: ID = pool_3
Type = Dynamic
Name = March2025
Description =
Total space = 3815810007040 (3.4T)
Current allocation = 20392058880 (18.9G)
Preallocated = 11551760384 (10.7G)
Remaining space = 3783866187776 (3.4T)
Subscription = 1182995120128 (1.0T)
Flash percent = 39%
Subscription percent = 31%
Alert threshold = 70%
Drives = 6 x 600.0G SAS; 6 x 400.0G SAS Flash 3
Number of drives = 12
RAID level = 5
Stripe length = 5
Rebalancing = no
Rebalancing progress =
Health state = Degraded/Warning (10)
Health details = "This storage pool exceeds the critical capacity threshold. Thin-provisioned resources may suffer data loss or become unavailable when the pool reaches full capacity. Snapshots may become invalid and replication sessions may stop synchronizing for storage resources provisioned in this pool. To allocate more storage space, add more disks to your system. (https://10.120.162.226/help/webhelp/en_US/index.html?#unity_c_storage_pool_at_or_near_full_capacity.html)"
2. Sätt in drivenheter efter behov och poolkrav.
3. Kontrollera att enheterna är online i Unisphere (UI).
4. Kontrollera diskgruppen som innehåller de okonfigurerade enheterna med följande kommando. Det här kommandot visar diskgruppen som innehåller de okonfigurerade enheterna.
uemcli /stor/config/dg -traditional show
Example:
1: ID = dg_28
Drive type = SAS Flash 3
FAST Cache = no
Drive size = 1575700986880 (1.4T)
Vendor size = 1.6T
Rotational speed = 0 rpm
Number of drives = 43
Unconfigured drives = 7
Capacity = 67755142435840 (61.6T)
Recommended number of spares = 25. Kontrollera profilen där enheterna ska läggas till med det här kommandot. Det här kommandot visar profilen där enheterna ska läggas till för att expandera poolen enligt RAID-gruppen. Kontrollera även vilken diskgrupp som tillhör den här profilen.
uemcli /stor/config/profile -traditional -configurable show
Example:
1: ID = tprofile_1
Type = Traditional
Description = SAS Flash RAID5 (4+1)
Drive type = SAS Flash
RAID level = 5
Maximum capacity = 7878504934400 (7.1T)
Stripe length = 5
Disk group = dg_28
Maximum drives to configure = 5
Maximum capacity to configure = 6302669729792 (5.7T)
6. Kör det här uemcli för att expandera poolen. I det här exemplet är diskgruppen dg_28är profilen tprofile_1är ID:t för den pool som ska utökas pool_1och antalet enheter för att utöka poolen är 5 enligt RAID Group. Efter att kommandot ger utdata som "Operation completed successfully."kontrollerar du antalet enheter och poolens status igen med hjälp av steg 1.
uemcli -d 10.0.0.0 -u admin -p 'MyPassword123!' /stor/config/pool -id pool_1 extend -diskGroup dg_28 -drivesNumber 5 -storProfile tprofile_1
