Instructions
Problem: Kan ikke udvide en pulje fra brugergrænsefladen.
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 i henhold til kravet. Kontroller RAID Group, og indsæt drev for at udvide puljen efter behov.
3. Kontrollér, om drevene er online med disse kommandoer:
fbecli.exe
pdo
Disse kommandoer viser antallet af drev og status for de drev, der er online. Match dette output med ovenstående output for at afgøre, om
pdo output har flere drev end puljen.
4. Kontroller diskgruppen, som indeholder de ikke-konfigurerede drev, med denne kommando:
uemcli /stor/config/dg -traditional show
Denne kommando viser den diskgruppe, der indeholder de ikke-konfigurerede drev.
Eksempel:
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 = 2- Kontroller profilen, hvor drevene skal tilføjes med denne kommando:
uemcli /stor/config/profile -traditional -configurable show
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.
Eksempel:
Eksempel:
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)
- Kør kommandoen uemcli for at udvide puljen:
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
I ovenstående 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.
Eksempel:
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
