Narrative:

I took the sector over and didn't notice an aircraft level at 10000 feet that indicated in the data block a climb to 17000 feet and there was a loss of separation with terrain. The previous controller released aircraft X to 10;000 feet. They removed the interim altitude of 10000 feet removed from the radar data block. Aircraft X checked on climbing to 10;000 feet. I plugged in for a position briefing. I took over the sector.aircraft X leveled at 10;000 feet while I was still 'nesting' after signing on to position. The MSAW alert went off and the aircraft requested a higher altitude. I asked him what altitude he would like and then I realized he wasn't climbing and issued a climb to 17;000 feet as the aircraft entered an 11000 foot minimum vectoring altitude. A low altitude alert was issued and pilot responded he had the terrain in sight. Don't remove interim altitude before issuing new altitude. Scan faster.
