Error description
The mounting of a snapshot by FlashCopy Manager to a Linux system for offloaded backup to Tivoli Storage Manager can show 2 different types of undesired behaviour: 1. Depending on the amount of generic SCSI devices, the snapshot mount can take a long time. 45 minutes have been reported. 2. Any attached tape drives are disconnected from that host by deletion of the associated /dev/sg... device, which leads to the abort of any Tivoli Storage Manager backup / restore. FlashCopy Manager does not report any error. Product versions affected: FlashCopy Manager version 4.1 on Linux Initial impact: Medium Additional keywords: FCM TSM XSF performance
Local fix
Avoid any Tivoli Storage Manager backup / restore activity on the backup host while the mounting of the snapshot takes place.
