Today when I arrived to the work I saw a email from Backup department about a restore failing the last Saturday. The error was the next;
channel aux12: ORA-27192: skgfcls: sbtclose2 returned error - failed to close file ORA-19511: non RMAN, but media manager or vendor specific failure, error text: We could not read the checksum. (0:3:2) ORA-19870: error while restoring backup piece WEBP_k3sq8u31_1_1 ORA-19501: read error on file "CLOUD_k3sf8t32_1_1", block number 1 (block size=512) ORA-27190: skgfrd: sbtread2 returned error ORA-19511: non RMAN, but media manager or vendor specific failure, error text: asdf_
After a bit of research I discovered the problem was in the network. This backup connect to serveral servers to work (Legato Server, a recover catalog and other database becouse of be a duplicate). Maybe a cut down of miliseconds order was enough to crash the restore. To verify the network stability and repeat the Rman Script solve the problem.
