Solution  1009194.1 :   Sun Fire[TM] 3800, v1280, E2900, 4800, 4810, E4900, 6800 and E6900 and Netra 1280, 1290: Can't boot from cdrom

Description
This article is to be used to aid in booting a cd rom from a Sun Fire[TM] server.

When booting from cdrom from a Sun Fire[TM] server, you receive the message:

ok> boot cdrom -s
ERROR: Can't open boot-device

Steps to Follow
The common resolution to this problem points to an incorrect devalias entry for the cdrom.
This is very common especially for configurations with the D240 with split back planes. It is therefore a good idea not to trust the default entries and verify/correct the cdrom entry in the OBP.

Procedure:

1. Issue the probe-scsi-all and sift through the outputs until you see the removable read-only device.
In our example the device path from an E6900 is at:

/ssm@0,0/pci@1e,700000/pci@1/scsi@2, target 6

------------------ end of output --------------------

2.  Set the alias for the removable read only device using nvalias and append disk@6,0:f.
Save the entry using the nvstore command.

{4} ok nvunalias cdrom
{4} ok nvalias cdrom /ssm@0,0/pci@1e,700000/pci@1/scsi@2/disk@6,0:f

3.  Reissue the command to boot the domain

{4} ok boot cdrom -s
