7. Before starting the patch application process, optionally adjust your disk_repair_time

ASM disk group attribute on each of your ASM disk groups to a higher value than 3.6 hour
default. This is often considered a “best practice” before patching to provide ASM more
time before dropping ASM disks from a disk group in the event a patch runs longer than
expected or encounters issues. Log in to your ASM instance as SYSASM and run the script
in Listing 11-1.

Listing 11-1. lst11-01-asm-repairtime.sql

SQL> @lst11-01-asm-repairtime.sql
SQL> alter diskgroup &&diskgroup_name set attribute
'disk_repair_time'='&&disk_repair_time';

At this point, you're ready to patch your storage cells. While logged in as root on the
compute node, change directories to the ExadataStorageServer patch directory and run
the following patchmgr command to patch your storage cells.

8.

■ When applying storage server patches using the -rolling option, patchmgr will iteratively apply the patches
to each storage cell defined in the cell_group file provided to the -cells command line argument. storage server
patches can take quite a bit of time to apply, so be patient while the patch is applying.
