Description
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.

Steps to Follow
Steps to Follow
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

     Resource              Information    
------------------  -------------------------

/dev/dsk/c1t1d0s2   Device being used by VxVM

#############################################

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

*NOTE that c1t3d0 is now unavailable and unconfigure Internal Comments
