Applies to:

Sun Fire X4500 Server - Version Not Applicable and later
All Platforms

Goal

How to determine the replacement disk slot location.

The /var/adm/messages file contains a failure message listed by marvellsx controller number and port number that must be translated to determine the replacement disk location.

Fix

Procedure to isolate the disk to replace

A failed disk results in the following type of message:

May 15 03:10:55 4500-boobear marvell88sx: [ID 812950 kern.warning] WARNING: marvell88sx5: error on port 2:

The following translation indicates the controller & its associated disk:

marvell88sxA: error on port B = sataA/B = Disk B on Marvell Controller A

In this example, Disk 2 on Marvell Controller 5 requires replacement (sata 5/2). The user must use cfgadm to map sata5/2 to the Solaris device name, as follows:

# cfgadm | grep sata5/2



 sata5/2::dsk/c7t2d0            disk         connected    configured   ok

Finally, use the hd utility to map solaris device name (/dev/dsk/c7t2d0) to the physical slot location:

# hd

In this example, marvell88sx5: error on port 2 maps to sata5/2, which maps to c7t2d0, which maps to the disk in slot #28.

Table 2.3 in Section 2.11 in service manual also shows the drive mappings by SATA port.
Take notice that the controller numbers shown along the top of FIGURE2-3 are not in numerial sequence.

Location of the HD utility's executable

The hd utility is pre-installed at the factory. If the system has been reinstalled then the utility may no longer be installed on the system.
If needed, the utility's executable is located in the SUNWhd package on the Tools and Drivers CD.
