Goal

Description

The goal of this document is to provide some guidelines for replacing disk storage, in the Solaris[TM] environment.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the appropriate community at My Oracle Support - Oracle Sun Technologies communities

Solution

Steps to Follow

Quickstart Reference for Sun disk replacement:

Caution

Any disk replacement should only be attempted by qualified service personnel, or with the assistance of a qualified person. This document is only intended as an introduction or reminder of the multiple software/hardware considerations that can affect a safe and successful disk replacement.

The full documentation should be consulted when anything is unclear - Oracle Documentation

Considerations

When planning to replace a disk, determine the following:

1. Is the system in question part of a cluster?

Details for cluster environments are outside of the scope of this document.
Reference Cluster documentation, or get assistance from Sun Support Personnel.

2. Is the device a software RAID device, or a hardware device?

You can tell this by looking at the application that's using the path. This is either a filesystem(UFS, ZFS, VxFS, SAMFS, QFS), or a raw database.

Commands to check:

# mount
# df -k

Hardware based disk device

/dev/dsk/c#t#d#s#

Software RAID device:

/dev/md/(r)dsk/d# (Solaris Volume Manager)
/dev/md/somemetasetname/(r)dsk/d#
/dev/vx/(r)dsk/somedg/somevol (Symantec Veritas Volume Manager)
/somepoolname (ZFS)

NOTE: if a disk is being used for raw access by a data base, it will not appear in mount or df -k.

Confirm this with a System administrator familiar with the system.

If the device is a software RAID device, you will want to review the status of that device to discover the hardware components of it. See the Software RAID section in this document.
If the device is a hardware RAID device, you will want to review the status of that device to discover the hardware component(s) that may have faulted. See the Hardware RAID section in this document.
If neither, continue.

3. Is the device an internal or external disk device?

If the device is an internal device you may want to review your hardware install guide and maintenance manual for your server, for replacement instructions.
If the device is an external device, you may want to review your hardware install guide and maintenance manual for your array.

Software RAID

ZFS

For replacement of devices that have been identified under ZFS, reference DocID: 1002753.1 How to Replace a Drive in Solaris[TM] ZFS

As a quick reference, you will want to check the following commands for device status:

zpool list
zpool status -v

Solaris[TM] Volume Manager

For replacement of devices that have been identified under Solaris Volume Manager,

Reference: DocID: 1006196.1 Solaris[TM] Volume Manager software: Replacing Disks (Solaris[TM] 9 Operating System and above)

As a quick reference, you will want to check the following commands for device status:

metastat
metadb -i

Symantec[TM] Veritas Volume Manager

As a quick reference, you will want to check the following commands for device status:status:

vxdisk list - Lists disks, shows if they're under VxVM
control, shows their current state. The "error" state indicates that
the disk is not under VxVM control. 
vxprint -ht - Lists volume configuration.

Hardware RAID

A1000/A3500FC/Raid Manager 6 (RM6)

For checking array health, use the RAID Manager 6 software, reference RAID Manager 6.2.2 User's Guide

As a quick reference, you will want to check the following commands:

/usr/lib/osa/bin/rm6

Launches management GUI for the hardware raid controllers. The Recovery Guru application in the GUI is
extremely useful for handling failure events

/usr/sbin/osa/lad

Lists c#t#d# of logical disks available in hardware

/usr/sbin/osa/drivutil -l <c#t#d#>

List individual disks in logical disk volume.

/usr/sbin/osa/healthck -a

Show array hardware status

Sun StorEdge[TM] T3 and Sun StorEdge[TM] 6120 arrays

For checking array health, reference DocID: 1009745.1 Troubleshooting Sun StorEdge[TM] T3 Disk Failures

As a quick reference, you will want to check the following commands after logging into the array shell via telnet:

fru stat

Field replaceable unit status

fru list

Field replaceable unit list

vol stat

Volume status

vol list

Volume list

proc list

Process list (Example: logical volume construction or recovery)

Sun StorEdge 3310, Sun StorEdge 3510 FC Array

For checking array health, reference, DocID: 1008190.1 Troubleshooting Sun StorEdge[TM] 33x0/351x Disk Failures

As a quick reference, you will want to check the following commands:

For in-band management (through SCSI or FCAL interface)

sccli - Starts command line interface (cli) for array management.

sccli> help

Displays cli commands available.

sccli> show configuration

Shows array components status

sccli> show disks

display status of disks, note: faulted disks do not appear in the listing.

sccli> show events

display system log

sccli> show FRUs

list fru's; contains part numbers and serial numbers.

sccli> show logical-drives

display LUN's and LUN status; shows if spare is configured and any failed disks.

sccli> show redundancy-mode

displays controller status
