Each letter under the “Disk Status” column represents a healthy drive at that channel as
shown in the figure above. Verify that all your drives can be seen by the S2A9550.
“Unhealthy” drives appear as follows:
• A “space” indicates that the drive is not present (or detected) at that location.
• A period (.) denotes that the disk was failed by the system.
• A question mark (?) indicates that the disk has failed the diagnostics tests or is not
configured correctly.
• The character “r” indicates that the disk at that location is being replaced by a spare
drive.
After entering the tier command, perform the following steps if necessary:
1.
If a drive is missing, ensure that the drive is properly seated and in good condition.
To search for the drive, use the command:
disk scan
<Enter>
.
2.
If the same channel is missing on all tiers, check the cable connections for that
channel.
3.
If “automatic disk rebuilding” is not enabled, enable it by using the command: tier
autorebuild=on
<Enter>
.
Use the
tier config
command to display the detailed disk configuration information for all
of the tiers ( Figure 2-8).
' Total LUNs ' indicates the number of LUNs which currently reside on the tier.
