Solution Type Technical Instruction Sure Solution 1009408.1 : Sun Fire[TM] V440 Server: How to Replace a Failed Internal Disk (non Hardware-RAID)
PreviouslyPublishedAs 213006 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 Audited/updated 12/02/09 - [email protected], Entry Level SPARC Content Team Member v440, 440, disk, replace, cfgadm, internal Previously Published As 80794 Change History Date: 2011-05-26 User name: Dencho Kojucharov Action: Currency check Comments: audited by Entry-Level SPARC Content Lead Date: 2006-10-06 User Name: 95826 Action: Approved Comment: - verified metadata - changed review date to 2007-10-05 - checked for TM - none added - checked audience : contract Publishing Version: 9 Date: 2006-10-06 User Name: 95826 Action: Accept Comment: Version: 0 Attachments This solution has no attachment |
