■ Within the HA-SAM environment, the nosam mount option must be specified for
any non-HA-SAM Sun StorageTek QFS file systems.
■ The HA-SAM resource, QFS file systems, and HAStoragePlus file systems must
all be configured within the same resource group. A separate Sun Cluster
resource group must be created for non-HA-SAM file systems.
■ When using the SUNW.hasam resource type, you cannot specify the /jointfilesconvert/483749/bg mount
option in the /etc/vfstab file.
■ Fibre tape drives are required. Tape drives must be visible to all systems through
the fibre fabric, but should not be configured as SAM-QFS shared drives.
■ Disk volumes for disk archiving must be visible to all nodes.
■ The active metadata server and potential metadata server must not be configured
as a SAM-Remote client or server.
■ The Sun StorageTek SAM catalog and stager directory must be in the default
location: /var/opt/SUNWsamfs/. If it is any other location, the cluster nodes
will not be able to locate it.
■ Before configuring HA-SAM, verify that all Sun StorageTek SAM operations are
working correctly on the required nodes in the cluster.
■ Only highly available (HA) agents are supported; no scalable agents are
supported.
■ Oracle software is not supported with this configuration, but the HA-SAM agent
is supported as an RMAN target for Oracle backups.
■ Voluntary failover forces a failover after five minutes in order to avoid problems
with other potential HA agents.
■ During voluntary failover, active archiving and staging times-out and terminates
after less than 5 minutes.
■ During failover, all SAM-QFS file systems must be failed over in order to avoid
complications with the recycler that could result in loss of data.
■ Sun StorageTek network attached tape libraries are supported, but not ADIC or
Sony 8400 PetaSite Series automated tape libraries.
■ HA-SAM environments cannot be managed by the File System Manager browser
interface.
■ During involuntary failover, error messages for idled tape drives may be seen in
the /var/adm/messages log file. These messages can safely be ignored. They
simply indicate that HA-SAM did not have time to idle the drives before failover.
■ After failover, volumes in the catalog may be marked with the E flag. This can
occur when the software is unable to write the correct label at the end of a tape.
To clear this error, see “To Clear Media Errors” on page 23.
