hdisk0 errors on the nodes sp21n7, sp21n8, sp21n9, and sp21n10, and performing
the pre- and post-actions:
1. Create .pre and .post scripts on one of the nodes. For example, create
2. Copy the .pre and .post files to the nodes sp21n8, sp21n9 and sp21n10 using
3. Create links to the EN_pend and EN_pend.envs scripts:
4. Add the notification object:

To remove this notification, enter:
penotify -w sp21n7,sp21n8,sp21n9,sp21n10 -f remove -n "hdisk0_err"
Important
Notification methods need to be accessible to each node that the notify object
is added to. We recommend that the notification scripts are kept local on
each node in case of network failure. File collections should be used to
maintain updates to notification methods.
