Solution 1019609.1 : ILOM 2.0.2.5 on Sun Fire x4500 may alter Solaris disk names.

Impact

After upgrading the ILOM on a Sun Fire X4500 to 2.0.2.5, if Solaris is reinstalled, and if the virtual CDROM and virtual floppy devices are not mapped in the JavaRConsole, several of the Solaris disk names may change. On newer systems shipped from the factory with ILOM 2.0.2.5 preinstalled, you may notice the boot disk and several other disks have different Solaris disk device names than prior shipped systems. This may cause confusion to the customer or the field.

Contributing Factors

Sun Fire X4500 upgraded to ILOM 2.0.2.5 may be impacted by this issue.
This is a result of a new SP features as explained in CR 6724613.

Symptoms

After ILOM 2.0.2.5 has been installed, C2 and C3 device names are no longer used by the SP and will become avaliable for disk device names causing a shift in several disk device names.

Root Cause

See Contributing Factors and Symptoms sections above.

Corrective Action

Workaround:

No workaround available - see Resolution section below.

Resolution:

Map both devices (CD-ROM and Floppy) in the JavaRConsole before reinstalling if PRE ILOM 2.0.2.5 disk drive mapping is desired.

For additional information on how the disks can differ, refer to:

Sun Fire X4500 Server Installation Guide (Sun P/N 819-4358-11) Section Titled:

"Important Solaris OS Installation and Bootable Hard Disk Drive Guidelines"
