Hari and Hara are the same.
The are the manifestation of the same Reality.
The appear to be different because of Functionality and the Approach of the Devotee.
When the are Human Form the show the world that the are the same b worshiping each other.

(My salutations to You Shaaswata! Sarva Mula Kaarana or the Root Cause of the Totality; Rishis affirm that you are the Master of Brahma; they assert that you are the Spring of the Three Gunas of Satwa-Rajasa-Tamasas; indeed you are the one residing in all the Lokas of Brahma, Vishnu, Vishwayoni, Agni, Samharta and also in Surya Mandala; You are the varied Forms of Praana, Hutavaha or Agni, Indra and all other Devaas; I have arrived into the shelter of Maha Deva; Saankhya Shastra Vedis extol you as the Singular and Gunaateeta Entity beyond Gunas and Maha Yogis are in constant search for you and perform ‘Upasana’; Vedas commend you as Rudra and Agni. Mahadeva! I seek indulgence and support! Human Beings place a flower or even a Bilwa Patra on your feet and you oblige them to get rid of the Shackles of Samsara! When Siddhaas and Yogis think of your sanctified feet sincerely, you are merciful to smash the burden of their sins!)

Shri Krishna eulogised Parameswara and fell on the feet of Shiva-Parvatis. As a gladdened Parvati was enjoying Krishna’s visit, Parama Shiva embraced Krishna and said: Krishna! You are indeed the bestower of wishes to one and all yourself! Krishna smiled and said that they knew indeed whatever he approached them for; but the boon that he sought was to bless him to secure a son as renowned as Maha Deva himself! As both Shiva and Parvati granted the wish, Shri Krishna visitited Kailasha for enjoyment and rerturned to Dwaraka. On his rerturn, Maharshi Markandeya arrived at Dwaraka and together they did the ‘Pratishtha’(installation) of a Shiva Linga and formal worship of the Shiva Linga. Consequent to Shiva Darshana, Krishna was blessed with the birth of Saambu from Devi Jambavati.
Krishna-Shiva’s Identity: Maharshi Markandeya wondered as to why Krishna who himself was worship-worthy and granted boons to his devotees, Krishna replied smilingly:
Bhavataa kathitam sarvam tathyameva na samshayaha,
Tathaapi Devameeshaanaam Pujayaami Sanaatanam/
Na mey vipraasti kartavyam naanavaaptam kathanchana,
Pujayaami tathaapeesham jaanannetat Param Shivam/
Na vai pashyanti tam Devam Maayayaa mohitaa janaah,
Tatoham swaatmano mulam jaapayanj pujayaami tam/
Na cha Lingaarchanaat Punyam Lokesmin bheetinaashanam,
Tathaa Linge hitaaaishaam lokaanaam Pujayecchivam/
Yoham tallingamityaahur Vedavaada vido janaah,
Tatohamaatma meeshaanam Puja- yaamyaatmanaiva tu/
Tasyaiva Paramaa Murtistanmayoham na samshayah,
Naavayorvidyatey bhedo Vedeyshvevam vinischayah/
Yesha Devo Mahaadevah sadaa samsaara bheerubhih,
Dhyeyaha Pujascha Vandyascha Jneyo Lingey Maheshwarah/
Krishna’s caution to Vishnu Bhaktas.
Paraat parataram yaanti Naraayana paraayanaah,
Na tey tatra gamishyanti ye dwishanti Maheswaram/
Dhyaanam homam Tapastaptam Jnaanam Yajnaadiko vidhih,
Teshaam Vinasyanti Kshipram ye nindanti Pinaakinam/
Yo maam samaashrayetrityamekaantam bhava- maashritah,
Vinindya Devameeshaanam sa yaanti narakaayutam/
Tasmaat saa Parihartavyaa nindaa Pashupatou Dwijaah,
Karmanaa Manasaa Vaachaa tadbhakteyshwapi yatnatah/
( Surely Narayana bhaktaas should be able to attain excellent Places of Mukti, but who ever think of Maheshwara with dislike would never ever reach any where! Those who keep hatred against and find fault with Shiva would be instantly be negated of their endeavours for Vishnu and their dhyaana, homa, Tapas and Yagnaadi Karyaas would be wasted in futility. What is worse, those who possess negative feelings for Mahadeva should be punished for thousand years of Naraka experiences. My warning to you Dwijaas therefore, Pashupati bhakti must always be retained by way of Karmanaa-Manasaa-Vaachaa means or by way of deeds-thoughts and speech in favour of Maha Deva!)
