Unconfiguring storage arrays 3–13
7. Log in to the system as follows:
login: root
password: secret
8. Unconfigure the arrays attached to the administration and MDS servers, as shown in the following
example, where there are two SFS20 arrays attached to the administration and MDS servers. Note
that you do not use the
unconfigure array
command to unconfigure these arrays; instead, you
use the
hpacucli
utility:
a. Start the
hpacucli
utility on the administration server by entering the following command:
# hpacucli
.
.
.
=>
b. Identify the numbers of the SFS20 arrays attached to the administration and MDS servers by
entering the following command:
=> controller all show
MSA20 at 01 (sn: P6C8CX7MQPS7UK)
MSA20 at 02 (sn: P92CBX3MQQX7KF)
Smart Array 6i in Slot 0 ()
Smart Array 6400 EM in Slot 2b(sn: P577C0G9SQF0K8)
Smart Array 6400 in Slot 2 (sn: P57820H9SQE6PW)
=>
This output shows two arrays, array
01
and array
02
.
c. Delete the contents of the arrays, as shown in the following example:
=> set target controller ch=01
controller chassisname=01
=> delete forced
=> set target controller ch=02
controller chassisname=02
=> delete forced
9. Reboot the administration server, by entering the following command:
# reboot
10. You must now reinstall the system, as described in Chapter 7 of the HP StorageWorks Scalable File
Share System Installation and Upgrade Guide. Start from Step 4 of the installation process
(Configuring the system parameters).
3.9.4 Unconfiguring SFS20 arrays attached to Object Storage Servers
CAUTION: This section relates to unconfiguring SFS20 arrays that are attached to Object Storage Servers
only. If you unconfigure an SFS20 array that is attached to the administration and MDS servers, you
effectively delete the entire HP SFS system configuration, and you must reinstall the system (see
Section 3.9.3 for more information).
It is possible to remove the configuration from an SFS20 array that is attached to an Object Storage Server
and restore the array to an unconfigured state; however, you cannot unconfigure an array while a LUN on
the array is in use. This means that you must shut down the servers, disable them, and then boot them again
before you unconfigure the array. The instructions for doing this are included in the procedure described
here.
CAUTION: When you unconfigure an SFS20 array, all of the user data on the array is lost.
