FCM: SAP/ORA: Change umount/rmfs order

See this idea on ideas.ibm.com

In case of Flashcopy Manager for Unix/Linux and the application SAP with Oracle DB: if the database must be restored/recovered, then the BRTools must be used.

If the BRtools are being started for brrestore/brrecover, then the FlashCopy Manager does the following:

foreach filesystem {
unmount filesystem
rmfs filesystem
}

This can lead to an error during brrestore if there is a handle on a mounted filesystem. In the worst case: if several sapdata filesystems are mounted and for only one or more of all filesystems the unmount fails, then brrestore will stop and finally some sapdatas remained, some sapdatas were deleted.

Unfortunately, then the brrestore tools cannont be restarted, because they require (due to internal check) ALL sapdata filesystems mounted. This only can be fixed if the volumes which the FCM removed before are created again manually. This is a very time consuming process in order to be able to retry the brrestore.

An advice for improvement would be this:

foreach filesystem {
unmount filesystem
}

if (all filesystems unmounted)
foreach filesystem {
rmfs filesystem
}

    This enhancement has been made available in FlashCopy Manager 3.2 and higher versions. FlashCopy Manager for Unix/Linux 4.1 is the latest version available to date.

    A check to see if the filesystem is in use, before attempting the restore, is absolutely necessary for my customer to adopt FCM. See PMR 41461,122,000 or Edmund Chun who told us: "According to FCM Development, the fuser check was used in previous iterations of the product, but when we moved on with the DB2 integration, DB2 strongly advised against running fuser so FCM development removed it. However, customers have been clamoring to add it back in." This RFE is supposedly the result of that clamoring, and so I add my vote here.
