Review Izimo Zokutholakala Okuphezulu Kweqoqo
Ukuqaliswa kwe-Cisco DNA Center kokutholakala okuphezulu (HA) kuchazwe kumhlahlandlela wokutholakala okuphezulu kwe-Cisco Digital Network Architecture Center High Availability. Sincoma ukuthi uqale kabushaview lolu lwazi bese unquma ukuthi uyafuna yini ukusebenzisa i-HA endaweni yakho yokukhiqiza. Uma ukhetha ukwenza kanjalo, qedela le misebenzi elandelayo:
- Qedela inqubo yokusebenzisa efanele inethiwekhi yakho:
• Ukuthunyelwa Okusha kwe-HA
• Ukukhishwa Okukhona Kwe-HA KweNodi Eyisisekelo Enokucushwa Kwe-Standard Interface
• Ukuthunyelwa Okukhona Kwe-HA Kwe-Primary Node Enokucushwa Kwe-Nonstandard Interface - Sabalalisa kabusha Amasevisi phakathi kwamanodi akho eqoqo.
- Bheka Ukucatshangelwa Okungeziwe Kokuthunyelwa kwe-HA futhi wenze noma yikuphi ukucupha okwengeziwe okudingekayo.
• Ukuthunyelwa Kwe-HA Okusha, ekhasini 1
• Ukuthunyelwa Okukhona Kwe-HA KweNodi Eyisisekelo Enokucushwa Kwe-Standard Interface, ekhasini lesi-2
• Ukuthunyelwa Okukhona Kwe-HA Okukhona Kwe-Primary Node Enokucushwa Kwe-Nonstandard Interface, ekhasini 2
• Sabalalisa kabusha Izinkonzo, ekhasini lesi-3
• Okunye Ukucatshangelwa Kokuthunyelwa kwe-HA, ekhasini lesi-3
Ukuthunyelwa Okusha kwe-HA
Ukufaka iqoqo le-HA elisha, qedela lezi zinyathelo ezilandelayo:
Isinyathelo 1
Lungiselela into yokuqala efakiwe njengenodi eyinhloko.
Bona Lungiselela Inodi Eyisisekelo.
Isinyathelo 2
Lungiselela izinto zikagesi zesibili nezesithathu kuqoqo.
Bona okuthi Lungiselela Ama-Add-Odes.
Ukukhishwa Okukhona Kwe-HA KweNodi Eyisisekelo Esezingeni Ukucushwa kwesixhumi esibonakalayo
Ukuze usebenzise iqoqo le-HA elikhona, lapho inodi eyinhloko isebenzisa ukulungiselelwa kwekhebula lesixhumi esibonakalayo esidingekayo, qedela izinyathelo ezilandelayo.
Isinyathelo 1
Thuthukisa indawo yokuqala ku-Cisco DNA Center 1.3.3.0.
Ukuze uthole ulwazi mayelana nokuthuthukisa ukukhishwa kwakho kwamanje kwe-Cisco DNA Center, bheka I-Cisco Digital Network Architecture Center Upgrade Guide.
Isinyathelo 2
Qinisekisa ukuthi usebenzisa ukulungiselelwa kwekhebula lesixhumi esibonakalayo esidingekayo endaweni eyinhloko.
Bheka Izixhumi Zekhebula le-Interface.
Isinyathelo 3
Buyekeza ikheli le-IP elibonakalayo (uma ikheli le-IP elibonakalayo lingakengezwa okwamanje).
Bona Ukumisa Kabusha Umshini Usebenzisa Iwizadi Yokucupha.
Isinyathelo 4
Lungiselela izinto zikagesi zesibili nezesithathu kuqoqo.
Bona okuthi Lungiselela Ama-Add-Odes.
Isinyathelo 5
Faka umyalo olandelayo ukuze uhlole usayizi we-GlusterFS: sudo.du-h/data/maglev/srv/maglev-system/glusterfs/mnt/bricks/default_brick/tail-1 | awk '{print $1}'
Uma i-GlusterFS file usayizi wesistimu mkhulu kuno-150 GB, qedela izinyathelo ezichazwe Ekusetshenzisweni Okukhona Kwe-HA KweNodi Eyisisekelo Ngokucushwa Kwe-Instandard Interface.
Ukuze usebenzise iqoqo le-HA elikhona lapho indawo eyinhloko isebenzisa ukulungiselelwa okungekhona okujwayelekile, qedela izinyathelo ezilandelayo.
Isinyathelo 1
Thuthukisa indawo yokuqala ku-Cisco DNA Center 1.3.3.0.
Ukuze uthole ulwazi mayelana nokuthuthukisa ukukhishwa kwakho kwamanje kwe-Cisco DNA Center, bheka Umhlahlandlela Wokuthuthukisa Isikhungo Se-Cisco DNA.
Isinyathelo 2
Dala isipele sekhosombe elikude.
Bheka isahluko esithi “Ikhophi Yasenqolobaneni Nokubuyisela” kumhlahlandlela Womqondisi Wesikhungo Se-Cisco DNA.
Isinyathelo 3
Cabanga kabusha indawo eyinhloko ngokucushwa kwekhebula lesixhumi esibonakalayo esidingekayo.
Bheka Izixhumanisi Zekhebula Le-Interface bese Ufaka Isithombe Se-ISO Sesikhungo Se-Cisco DNA. Qiniseka ukuthi i-VIP imiswe ngendlela efanele endaweni yokuqala.
Isinyathelo 4
Kunodi eyinhloko, faka isethi efanayo yamaphakheji oyikhethile ngesikhathi sokulondoloza.
Isinyathelo 5
Ukusebenzisa isipele file oyidalile esinyathelweni sesi-2, buyisela idatha yendawo yesikhombi esikude.
Isinyathelo 6
Lungiselela izinto zikagesi zesibili nezesithathu kuqoqo.
Bona okuthi Lungiselela Ama-Add-Odes.
Sabalalisa kabusha Amasevisi
Ukuqaliswa kwe-Cisco DNA Center kwe-HA kuchazwe ku-Cisco Digital Network Architecture Center High Availability Guide. Sincoma ukuthi uqale kabushaview lolu lwazi bese unquma ukuthi uyafuna yini ukusebenzisa i-HA endaweni yakho yokukhiqiza. Uma ukhetha ukwenza kanjalo, lungiselela ukusebenza kwe-HA ngokusabalalisa kabusha izinsiza phakathi kwamanodi akho eqoqo:
- Kusuka ekhasini lasekhaya, chofoza bese ukhetha Izilungiselelo Zesistimu.
Ithebhu ye-System 360 iboniswa ngokuzenzakalelayo. - Endaweni yabasingathi, chofoza Vumela Ukusabalalisa Isevisi.
Ngemva kokuchofoza Vumela Ukusabalalisa Kwesevisi, i-Cisco DNA Center ingena kumodi yesondlo. Kule modi, i-Cisco DNA Center ayitholakali kuze kuqedwe ukusabalalisa kabusha kwezinsizakalo. Kufanele ukucabangele lokhu lapho uhlela ukuthunyelwa kwe-HA.
Qaphela
I-Cisco DNA Center ingena kumodi yokulungisa njalo uma ubuyisela isizindalwazi, wenza ukuthuthukiswa kwesistimu (hhayi ukuthuthukiswa kwephakheji), futhi unike amandla ukusabalalisa kabusha kwesevisi ye-HA (njengoba kuchazwe ngenhla).
Ukucatshangelwa Okungeziwe Kokuthunyelwa kwe-HA
Ukuze kusetshenziswe i-HA ekhona, ukulungiselelwa okwengeziwe okulandelayo kufanele kwenziwe.
Qaphela
Ukuze uthole ulwazi mayelana neziphazamisi ze-HA ezaziwayo nezindlela zokusebenza, bona okuthi “Vula Iziphazamisi—HA” kokuthi Amanothi Okukhishwa e-Cisco Digital Network Architecture Center.
I-Telemetry
Uma unike amandla i-telemetry kudivayisi (ngaphandle kokuvumela i-VIP), qedela lezi zinyathelo ezilandelayo:
Isinyathelo 1
Sebenzisa umyalo wokubuyekeza i-maglev-config ukuze ubuyekeze i-VIP yeqoqo.
Isinyathelo 2
Khubaza i-telemetry kudivayisi:
a. Kusuka ekhasini lasekhaya leCisco DNA Center, khetha i-Network Telemetry endaweni yamathuluzi.
Iwindi le-Network Telemetry liyavela.
b. Chofoza Isayithi View ithebhu.
c. Hlola ibhokisi lokuhlola ledivayisi ofuna ukukhubaza kuyo i-telemetry, bese ukhetha Izenzo > Khubaza i-Telemetry.
Isinyathelo 3
Nika amandla kabusha i-telemetry usebenzisa i-profile ezihlobene nedivayisi ngaphambilini.
Isilawuli Esingenantambo
Kufanele ubuyekeze izilawuli ezingenantambo kunethiwekhi yakho nge-VIP entsha ye-Cisco DNA Center.
