Configuring the DP-VOL protection function options

Use this procedure to configure (enable or disable) the DP-VOL protection function options on an existing pool.

The DP-VOL protection function options are:

  • Protect V-VOLs when I/O fails to Full Pool Enable this option to protect the DP-VOLs using the pool from read and write requests when the pool usage reaches the full size.
  • Protect V-VOLs when I/O fails to Blocked Pool VOL Enable this option to protect the DP-VOLs using the pool from read and write requests when the pool-VOL is blocked.

NoteWhen either of these options is enabled for a Dynamic Provisioning pool that contains Thin Image pairs and snapshot data, if pool VOLs are blocked or the pool is full, only DP-VOLs are protected.
