Symptoms

We have a disk that needs to be replaced but we do not know which Physical Disk matches the bad disk identified in software commands

Changes

A problem with a disk has resulted in needing to replace it. However, there are many disks in the ODA configuration.

Cause

Bad or predictive failure for an ODA disk detected

Solution

Use the following oakcli command to turn the LED ON or OFF.
This helps technicians properly identify the disk needing replacement.

oakcli locate disk <diskname> <on | off>

where:
on - turns on the LED of the given disk
off - turns off the LED of the given disk

Examples

Usage on X3-2, X4-2 or X5-2

[root@odax31 ~]# oakcli locate disk e0_pd_00 on

Disk: e0_pd_00 and to: ON

[root@odax31 ~]# oakcli locate disk e0_pd_00 off

Disk: e0_pd_00 and to: OFF

Usage on V1

[root@oda1-base ~]# oakcli locate disk pd_00 on

Disk: pd_00 and to: ON

[root@oda2-base ~]# oakcli locate disk pd_00 off

Disk: pd_00 and to: OFF

COMMENTS

The format is different depending on the HW version used.
As of X3-2 and higher the disk name is also dependent on the Storage Shelf Number

V1 will use pd_XX format for the disk name

X3-2, X4-2, X5-2 will use e[0|1]_pd_xx

                             - where e0 is for the original JBOD (storage shelf)
                                         e1 is for the second JBOD (optional storage shelf)

X3-2 and higher:The Disk Name uses a prefix of e0 or e1

[root@odax3rm1 ~]# oakcli show disk
        NAME            PATH            TYPE            STATE           STATE_DETAILS

        e0_pd_03        /dev/sdbv       HDD             ONLINE          Good
        e0_pd_04 <<     /dev/sdbw       HDD             OFFLINE         Bad

        e0_pd_23        /dev/sdcp       SSD             ONLINE          Good
        e1_pd_00        /dev/sdav       HDD             ONLINE          Good
        e1_pd_01        /dev/sdaw       HDD             ONLINE          Good
        e1_pd_02        /dev/sdax       HDD             ONLINE          Good
        e1_pd_03        /dev/sdaa       HDD             ONLINE          Good

V1: The Disk Name uses pd_xx with no e0 or e1 prefix

[root@odarm2-base ~]# oakcli show disk
        NAME            PATH            TYPE            STATE           STATE_DETAILS

        pd_00           /dev/sda        HDD             ONLINE          Good
        pd_01           /dev/sdk        HDD             ONLINE          Good
        pd_02           /dev/sdm        HDD             ONLINE          Good
        pd_03           /dev/sdw        HDD             ONLINE          Good
