All Linux users with Qlogic adapters are advised to upgrade the QLogic driver to 8.07.00.16-k.
This driver upgrade enables the Linux client to handle correctly any warmstarts that occur in an Oracle FS System Controller.
Qlogic adapters without this driver upgrade do not properly logout after a Controller warmstart. The improper logout requires the Oracle FS System software to recognize that condition and to force an explicit logout. Usually this handling succeeds. When this handling does not succeed, loss of I/O from the adapter to the LUNs on that Controller can result.
