Hello,
we have just installed a new server and encounter a
serious problem. The storage pool /dev/rstorage_pool
is always set to readonly after a short time of usage
without any disk errors in the AIX errorlog!
Thereafter all backups go directly to tape. Because we
have at the moment only 2 drives attached, backups are
nearly impossible. Any hints or advises?
