Symantec NetBackup - Frequently asked questions about Shared Storage Option

■ Verify that you did not interrupt a data path during a backup. If you do, the
NetBackup job fails. It can fail with media write errors or it may hang and have
to be terminated manually.
■ Verify that you do not use Berkeley-style close on the tape path (UNIX or Linux
servers only).
■ On Solaris systems, verify the following:
■ That you added tape configuration list entries in /kernel/drv/st.conf (if
needed).
■ That you defined configuration entries for expanded targets and LUNs in
sg.links and sg.conf files. If you see problems with the entries in the
/etc/devlink.tab file (created from sg.links), verify the following:
The first entry uses hexadecimal notation for the target and LUN. The
second entry uses decimal notation for the target and LUN.
Use a single tab character between the entries; do not use a space or a space
and a tab character.
■ That you configured the operating system to force load the sg/st/fcaw
drivers.
For more information, see the Solaris chapter of the NetBackup Device
Configuration Guide.

Q. If NetBackup allocates four drives to a server and it finishes with two of the
drives, does NetBackup reallocate the two drives? Or does NetBackup wait until

reallocates the drives?
