PreviouslyPublishedAs 204282 Understanding and setting up boot devices on an E3500.
Applies to:Sun Enterprise 3500 ServerAll Platforms GoalUnderstanding and setting up boot devices on a Sun Enterprise 3500Understanding full physical paths on an E3500 in relation to the onboard disk drives is important when selecting a boot device.SolutionThere are four ports on the interface board (IB) labeled top to bottom:UB, UA, LB, LA This photo shows an FC-AL IB laying on it's side. To access these ports you must come off either:
The full physical device address describes:
The upper drives and the lower drives act as two separate arrays. Use the "probe-fcal-all" command and the disk World-Wide Number (WWN) to determine which array (top or bottom) your disk is on.The following is a breakdown of a complete physical path:
How to identify which port on the host IB board:(W21=UA/LA, W22=UB/LB) identifies if cable plugs onto A or B on the interface board, but does NOT identify whether top or bottom drives. (top and bottom are 2 separate arrays). Using the above information you should be able to make an alias to boot from any internal drive as follows:
1. Select an alias name: <myinternaldisk>. 2. Type the following at the ok> prompt: (Use the above example to fill in numbers for A, B, C, D, E ,F, and G).ok> nvalias /sbus@A,0/SUNW,socal@B,10000/sf@C,0/ssd@w2DEEEEEEEEEEEEEE,F:G 3. Copy the contents of the command into nvramrc: 4. Add the alias to the boot device list.ok> nvstore 5. Reset the system.ok> setenv boot-device [disk] [net] 6. Boot the server. You will not need this step if auto-boot is set to true.ok> reset-all ok> boot From the Installation Guide (pdf), section 2-15:External SCSI-2 devices connect to your system through the built-in single-ended Fast/Wide SCSI-2 port on I/O+ boards (except for the board in slot 1), or through FSBE/S, DSBE/S, SWIS/S, or DWIS/S SBus cards installed on I/O+ boards.Note - The onboard SCSI-2 bus on the I/O+ board in slot 1 controls internal media tray devices. Therefore, the external SCSI connector on the I/O+ board in slot 1 must always have a terminator installed.@ Internal Comments nvalias, e3500, boot, device, path Previously Published As 40562 Attachments This solution has no attachment |
