You should return disk07 OR disk08 online, then data will be resilvered.
Do not replace until you got DEGRADED instead of UNAVAIL.

I have a serious problem with my storage:
Zpool is exported from system.

	    gpt/disk07  UNAVAIL  cannot open
	    gpt/disk08  UNAVAIL  cannot open
	    gpt/disk17  UNAVAIL  cannot open

Where did these disks go? 3 disks missing could indicate a cabling problem, expansion chassis not powered on, and so forth. Do all of the expected drives appear in the BIOS / controller card management menu, and so forth? I think you have a hardware issue which needs to be resolved before you can re-import the pool.
