# mmstartup -N <node class name>

d. Ensure that node servers are active before you do the next step by issuing the following

command:

# mmgetstate -a

You can use the following command also to check the pagepool:

# mmvdisk server list --nc <node class name> --config

Example

[root@ess3k5a ~]# mmvdisk server list --nc ess_x86_64_mmvdisk_5 --config

e. Turn on the GPFS automount by issuing the following command:

# mmchfs <filesystem> -A yes

f. Turn on the GPFS autoload by issuing the following command:

# mmchconfig autoload=yes

g. Double check and conrm that the GPFS automount is enabled by issuing the following command:

# mmlsfs <filesystem name>

h. Ensure that autoload=yes is under the node class entry that is associated with the target ESS

3000 by issuing the following command:

# mmlsconfig

9. Mount the le system (customer task).

a. Mount each le system individually by issuing the following command:

# mmmount <filesystem> -a

b. If you want to mount all le systems in all nodes, you can issue the following command:

# mmmount all -N all

c. Ensure that the le systems are up.

d. Conrm that one or more target le systems are mounted by issuing the following command:

# mmlsmount <filesystem> -L

10. Do health check by issuing the following command, and resume I/O because the MES is complete

(customer task):

# mmhealth node show

ESS 3000 storage drives concurrent MES upgrade
