Chapter 4 Maintenance
4.1 Upgrading the JBOD Controller Firmware
NOTE: The JBOD firmware upgrade procedure must be done three
times. First is on the JBOD Controller, next is on the Expander
Module 1-1, then last on the Expander Module 1-2.
NOTE: There must be no I/O in the disk drives in the JetStor SAS
742JD (RAID volumes should not be accessed) during firmware
upgrade.
A VT100 compatible terminal or a PC operating in an equivalent terminal emulation
mode is needed to upgrade the firmware.
NOTE: It is important to stop I/O access to JetStor SAS 742JD during
firmware upgrade.
NOTE: Upgrading the firmware must be done from Master JBOD
Controller if the JetStor SAS 742JD has redundant JBOD Controllers.
