Dell Unity: Unity-varannon laajentaminen komentoriviliittymässä
Summary: Tässä artikkelissa kerrotaan, miten olemassa olevaa Dell Unity -tallennusvarantoa laajennetaan lisäämällä uusi levyryhmä Unity Enterprise Management CLI (UEMCLI) -komentoriviliittymän avulla. Esimerkissä esitellään poolin laajennuskomento, joka sisältää tarvittavat parametrit, kuten varannon tunnuksen, levyryhmän tunnuksen, asemien määrän ja tallennusprofiilin. Toimenpiteen avulla voidaan lisätä käytettävissä olevaa kapasiteettia säilyttäen samalla halutut tallennustasot ja varannon suorituskykyominaisuudet. ...

Instructions
1. Tarkista varannon tila sekä hae aseman ja RAID-ryhmän tiedot:
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. Aseta asemat tarpeen ja varannon vaatimusten mukaisesti.
3. Varmista, että asemat ovat online-tilassa Unispheressa (UI).
4. Tarkista määrittämättömät asemat sisältävä levyryhmä seuraavalla komennolla. Tämä komento näyttää levyryhmän, joka sisältää määrittämättömät asemat.
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. Tarkista profiili, johon asemat lisätään, tällä komennolla. Tämä komento näyttää profiilin, johon asemat lisätään, jotta varantoa voidaan laajentaa RAID-ryhmän mukaan. Tarkista myös profiiliin kuuluva levyryhmä.
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. Suorita tämä uemcli komento varannon laajentamiseksi. Tässä esimerkissä Levy-ryhmä on dg_28, profiili on tprofile_1, laajennettavan poolin tunnus on pool_1, ja varannon laajentamiseen tarvittavien asemien määrä on RAID Groupin mukaan 5. Kun komento antaa tuloksen muodossa "Operation completed successfully.", tarkista asemien määrä ja varannon tila uudelleen vaiheessa 1.
