c. Type the following to check that the necessary file systems are mounted:
# df –h
6. [ ] Check that the Blades are running normally:
# /nasmcd/sbin/getreason –e
Expected output:
10 - slot_0 primary control station
5 - slot_2 contacted(Post Code = 0x61 ; Mid Code = 0x80 ; Blade Code = 0x2c
5 - slot_3 contacted(Post Code = 0x61 ; Mid Code = 0x80 ; Blade Code = 0x2c
7. [ ] For a multi-BE system, if any of the Blades in the replacement enclosure were failed over to a
standby Blade housed in another BE in Prepare DME Replacement, complete the following to fully
failback the Blade.
a. If this is single-BE system or no Blades are in a failed over state go to the next step:
b. Restore the Blades to the configured primary/standby Blade relationship by typing the following
command:
Note: This command requires several minutes to complete. Wait until this command has completed before
continuing.
# /nas/bin/server_standby <server_name> –restore mover
where <server_name> is the name of the standby Blade functioning as the primary Blade.
Example:
Suppose Blade 3 is a standby Blade for Blade 2 and Blade 2 has failed over to Blade 3. The command
to restore Blade 2 as the primary Blade is:
# /nas/bin/server_standby server_2 -restore mover
Sample Output:
server_2 :
server_2 : going standby
server_2.faulted.server_3 : going active
replace in progress ...done
failover activity complete
commit in progress (not interruptible)...done
server_2 : renamed as server_3
server_2.faulted.server_3 : renamed as server_2
8. [ ] If you removed a standby relationship in Prepare DME Replacement, reestablish this relationship
by entering the following command for each standby relationship previously removed.
# /nas/bin/server_standby <primary_server_name> -create mover=
<standby_server_name>-policy <policy_type>
where:
 <primary_server_name> is the name of the designated primary Blade
 <standby_server_name> is the name of the Blade designated standby Blade
 <policy_type> is the failover policy; EMC recommends an auto failover policy
