Solution 1009408.1 : How to Replace a Failed Internal Disk (non Hardware-RAID) on V440 Server

Applies to:

Sun Fire V440 Server - Version Not Applicable and later
Sun Fire V445 Server - Version Not Applicable and later
All Platforms

Goal

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - SPARC Legacy Servers

This document describes the process of replacing a failed internal
disk on the Sun Fire[TM] V440 server when the disk is not mirrored using the on-board hardware RAID controller.

Solution

1. Verify which disk drive corresponds with which logical device name and physical device name. Listed below is the table for the v440 disk devices:

Disk Slot Number    Logical Device Name[1]             Physical Device Name
-----------------------------------------------------------------------------
Slot 0            c1t0d0                /devices/pci@1f,700000/scsi@2/sd@0,0
Slot 1            c1t1d0                /devices/pci@1f,700000/scsi@2/sd@1,0
Slot 2            c1t2d0                /devices/pci@1f,700000/scsi@2/sd@2,0
Slot 3            c1t3d0                /devices/pci@1f,700000/scsi@2/sd@3,0

2. Verify that a hardware disk mirror does not exist

# raidctl
No RAID volumes found.

****NOTE**** If Raid volumes exist see Technical Instruction <Document: 1009043.1> Sun Fire[TM] V440 Server: How to Replace a Failed Disk Mirrored with the raidctl Command.

3. View status of SCSI devices

# cfgadm -al
Ap_Id             Type            Receptacle   Occupant     Condition
c0                scsi-bus        connected    configured   unknown
c0::dsk/c0t0d0    CD-ROM          connected    configured   unknown
c1                scsi-bus        connected    configured   unknown
c1::dsk/c1t0d0    disk            connected    configured   unknown
c1::dsk/c1t1d0    disk            connected    configured   unknown
c1::dsk/c1t2d0    disk            connected    configured   unknown
c1::dsk/c1t3d0    disk            connected    configured   unknown
c2                scsi-bus        connected    configured   unknown
c2::dsk/c2t2d0    disk            connected    configured   unknown
usb0/1            unknown         empty        unconfigured ok
usb0/2            unknown         empty        unconfigured ok
usb1/1            unknown         empty        unconfigured ok
usb1/2            unknown         empty        unconfigured ok

4. Remove the disk drive from the device tree

# cfgadm -c unconfigure <Ap_Id>
example -> #cfgadm -c unconfigure c1::dsk/c1t3d0

This example removes c1t3d0 from the device tree. The blue OK-to-Remve LED for the disk being removed will become lit.

NOTE:
- maybe necessary to use "-f" (force) option if device is managed by Multipathing software such as vxdmp and since there is only a single path to device (ie. internal devices)

example:

ohio122{root}:/# cfgadm -c unconfigure c1::dsk/c1t1d0

Sep 15 04:35:29 ohio122 rcm_daemon[4325]: rcm script es_rcm.pl: VxVM vxdmpadm ERROR V-5-1-5122 Attempt to disable path failed. Last path to the root disk can not be disabled. use option -f otherwise.

cfgadm: Component system is busy, try again: failed to offline: /devices/pci@1f,700000/scsi@2/sd@1,0

5. Verify that the device has been removed from the device tree

#cfgadm -al
Ap_Id             Type            Receptacle   Occupant     Condition
c0                scsi-bus        connected    configured   unknown
c0::dsk/c0t0d0    CD-ROM          connected    configured   unknown
c1                scsi-bus        connected    configured   unknown
c1::dsk/c1t0d0    disk            connected    configured   unknown
c1::dsk/c1t1d0    disk            connected    configured   unknown
c1::dsk/c1t2d0    disk            connected    configured   unknown
c1::dsk/c1t3d0    unavailable     connected    unconfigured unknown
c2                scsi-bus        connected    configured   unknown
c2::dsk/c2t2d0    disk            connected    configured   unknown
usb0/1            unknown         empty        unconfigured ok
usb0/2            unknown         empty        unconfigured ok
usb1/1            unknown         empty        unconfigured ok
usb1/2            unknown         empty        unconfigured ok

c1t3d0 is now unavailable and unconfigured
