Dell Unity: Sådan udvider du en Unity-pulje ved hjælp af CLI
Summary: Denne artikel beskriver, hvordan du bruger Unity Enterprise Management CLI (UEMCLI) til at udvide en eksisterende Dell Unity-storagepulje ved at tilføje en ny diskgruppe. Eksemplet viser kommandoen til udvidelse af puljen, herunder de påkrævede parametre som f.eks. pulje-id, diskgruppe-id, antal drev og lagerprofil. Proceduren kan bruges til at øge den tilgængelige kapacitet, samtidig med at puljens ønskede niveauinddeling og ydeevne bevares. ...

Instructions
1. Kontrollér status for puljen, og få oplysninger om drev og RAID-gruppe:
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. Indsæt drev efter behov og puljekrav.
3. Kontroller, at drevene er online i Unisphere (UI).
4. Kontroller diskgruppen, som indeholder de ikke-konfigurerede drev med følgende kommando. Denne kommando viser den diskgruppe, der indeholder de ikke-konfigurerede drev.
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. Kontroller profilen, hvor drevene skal tilføjes med denne kommando. Denne kommando viser den profil, hvor drevene skal tilføjes for at udvide puljen i henhold til RAID-gruppen. Kontroller også den diskgruppe, der hører til denne 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. Kør dette uemcli kommando til at udvide puljen. I dette eksempel er diskgruppen dg_28, profilen er tprofile_1, er id'et for den pulje, der skal udvides, pool_1, og antallet af drev, der skal udvides puljen, er 5 ifølge RAID Group. Efter kommandoen giver output som "Operation completed successfully.", skal du kontrollere antallet af drev og puljestatus igen ved hjælp af trin 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
