Missing storage pool


trublu

Question

Had issues after upgrading to DSM 7.1.1-42962 Update 4. After changing to ARPL 1.03b, I was able to recover the system after a migration and log into a fresh DSM, however, the storage pool is missing/lost. Looking for tips on how to rebuild the original storage pool. Thanks.

 

Hardware:

Motherboard with UEFi disabled: SUPERMICRO X10SDV-TLN4F D-1541 (2 x 10 GbE LAN & 2 x Intel i350-AM2 GbE LAN)

LSI HBA with 8 HDDs (onboard STA controllers disabled)
