Remove a Storage Array HDD or SSD (CRU)
Enter the appropriate commands through the CLI to prepare the drive for
1.
removal from the storage array.
Use this procedure to logically remove a storage array drive from the system before you
physically remove the drive.
The length of time that it takes to complete this procedure before you can physically remove the
drive depends on the type of drive you are removing:
SSD – The detach operation completes quickly and the drive can be removed immediately.
■
HDD – The detach operation takes several minutes to complete. Do not remove the drive
■
before the detach operation competes.
a.
Log into the mcmu CLI as a primary admin such as mcinstall.
% ssh mcinstall@minicluster_node_name_or_IPaddress
where minicluster_node_name_or_IPaddress is the name of the first node on MiniCluster,
or the IP address of the first node.
For example:
% ssh mcinstall@mc4-n1
b. When prompted, enter the password.
For more information about running mcmu CLI commands, refer to the Oracle MiniCluster
S7-2 Installation Guide or the Oracle MiniCluster S7-2 Administration Guide.
Identify the drive name.
c.
You might be able to get the drive name from the error message or log file that led to the
plan to replace the drive.
You can use a command such as diskinfo. Make note of the long drive name (such as
c0t5000CCA23B0BF34Cd0) for use with this procedure. Also make note of the shorter name
(such as HDD8) for use with the followup task when you reattach the replaced drive.
Also note that the storage array drives are identified by a JBODARRAY string.
For example:
% diskinfo
D:devchassis-path
