Dell Unity : Extension d’un pool Unity à l’aide de la CLI
Summary: Cet article explique comment utiliser la CLI de gestion d’entreprise Unity (UEMCLI) pour étendre un pool de stockage Dell Unity existant en ajoutant un nouveau groupe de disques. L’exemple illustre la commande d’extension de pool, y compris les paramètres requis tels que l’ID de pool, l’ID du groupe de disques, le nombre de disques et le profil de stockage. Cette procédure peut être utilisée pour augmenter la capacité disponible tout en conservant la hiérarchisation du stockage et les caractéristiques de performances souhaitées du pool. ...

Instructions
1. Vérifiez l’état du pool et obtenez des informations sur le groupe de disques et RAID :
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. Insérez des disques en fonction des besoins et des exigences du pool.
3. Vérifiez que les disques sont en ligne dans Unisphere (IU).
4. Vérifiez le groupe de disques qui contient les lecteurs non configurés à l’aide de la commande suivante. Cette commande affiche le groupe de disques qui contient les disques non configurés.
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. Vérifiez le profil dans lequel les disques doivent être ajoutés à l’aide de cette commande. Cette commande affiche le profil dans lequel les disques doivent être ajoutés pour étendre le pool en fonction du groupe RAID. Vérifiez également le groupe de disques qui appartient à ce profil.
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. Exécutez ceci uemcli pour développer le pool. Dans cet exemple, le groupe de disques est dg_28, le profil est tprofile_1, l’ID du pool à développer est pool_1, et le nombre de disques pour étendre le pool est de 5 selon le groupe RAID. Une fois que la commande donne le résultat en tant que "Operation completed successfully.", vérifiez à nouveau le nombre de lecteurs et l’état du pool à l’aide de l’étape 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
Example:
15:12:26 root@xyz spb:/cores/service/user> uemcli /stor/config/pool show -detail
Storage system address: 127.0.0.1
Storage system port: 443
