Adding SC280 Enclosures
UsecautionwhenaddinganenclosuretoaliveStorageCentersystemtopreservethe
integrityoftheexistingdata.Thissectiondescribestwomethodsofaddingenclosures:
 Addanenclosureinanewchain:byaddingenclosurestoavailableportsonthe
controller’sIOcards.Thecurrentconfigurationisundisturbed.Creatinganewchainis
thesafestwaytoincreasestoragecapacity.Whenyouhavemultiplechains,youshould
haveatleasttwoIOcardsineachcontroller.
 Addanenclosuretoanexistingchainbyremovingonesideofthechaincausingtraffic
toroutetotheremainingside.Connectthenewenclosureintothedisconnectedsideof
thechain.
Adding an SC280 Enclosure in a New Chain
Thismethodissafeandnon‐intrusivetotheexistingdisksandchains.Asecondchain
createscontrollerredundancyandsoIPCcross‐overcablesarenotrequired.
Check Lead Controller
IdentifytheleadcontrollerbycheckingcontrollersummaryinformationinSystem
Manager.ThesecablinginstructionsassumethatControllerAisthelead controller.
1 IntheStorageCenterSystemManager,selecttheControllersnode.
2 Inthecontrollersummarypanenotewhichcontrollerisidentifiedastheleader.
Connect the Enclosure
1 Turnoneachenclosurebeingadded.Whentheenclosuresspinup,makesurethat
eachfrontpanelenclosureandpowerstatusLEDsshownormaloperation.
2 ConnecttheAside(Figure111onpage 176):
a ConnectControllerA: slot3,port2→Enclosur e2:left,portC.
b ConnectControllerB:slot
3,port4→Enclosure2:left,portB.
3 ConnecttheB side(Figure 112onpage 177):
a ConnectControllerA: slot3,port4→Enclosur e2:right,portB.
b ConnectControllerB:slot3,port2→Enclosure2:right,portC.
4 IntheStorageCenterSystemManager,selectStorageManagement
→System→
Setup→ConfigureLocalPorts.
5 Makesurethat:
 SlotandslotportsareUpandthePurposeissettoback‐end.
 TargetCountequalsthenumberofaddeddrives,demonstratingthatthecontroller
recognizesthenewenclosures.
6 IntheStorageManagerSystemTree,confirmthenumberofenclosures.
Iftherearenomanageddisksinthissystem,theSystemManagerdoesnotassignan
Indexnumber.Ifthesystemcontainsamanaged
diskinanyenclosure,theSystem
Managerassignsanindexnumbertothenewenclosures.
Note: Enclosuresmustberunningthecurrentversionoffirmwarebefore
managingthedrivesinStorageCenterSystemManager.
