2. After checking the lpp_source , NIM, or directory for file updates by using the -Q  flag, you can perform the installation on the server.

3. Back up your date before performing any upgrades on your servers. The alt_disk_copy tool makes a mirror copy of your rootvg to another disk in a separate VG and Object Data Manager (ODM). The cl_ezupdate  tool may perform the backup while rolling your updates, or before you perform the updates by using the flag -X  or -x : 

/usr/es/sbin/cluster/utilities/cl_ezupdate -X -N bolsilludo2:hdisk6
