Oracle HSM (SAQFS): Preventing Disk LUNs In a Clustered Environment From Becoming Unresponsive or Mounted Read-Only
Last updated on DECEMBER 20, 2017
Applies to:Oracle Hierarchical Storage Manager (HSM) and StorageTek QFS Software - Version 5.0 and later
Information in this document applies to any platform.
In some occasions it can occur that after a cluster node reboot or a restart of some cluster resources, some or all of the samfs filesystems fail to mount correctly or mount in read-only mode. In several of these occasions this was caused by the cluster framework putting scsi-reservations on the data luns and thus preventing another node or a qfs client outside the cluster (COTC) from accessing these LUN's correctly.
