StorageWorks Secure Path for Windows NT

6-10 123995-002 EK-WNTMP-MH. D01

6.9 Automatic Failback

Auto-failback monitors a failed path and will automatically return failed-over storage

units to their original path, once the path has been restored. With auto-failback enabled,

Secure Path will attempt to failback a unit only twice within one hour. After two attempts,

Secure Path will cancel further failback attempts to prevent repeatedly switching the

storage unit(s) between paths.

As shown in Figure 6-7, auto-failback may be enabled or disabled through use of the

AutoFailBack pull-down menu in the Secure Path Manager.

Figure 6–7 Enabling the Auto-Failback Feature

NOTES

Auto-failback is a

global

parameter that will affect all

storage units configured on all Secure Path managed

subsystems.

Even with the auto-failback feature enabled,

manual failback

of storage units (described in Section 6.9) can still be

performed at any time, once the path’s integrity is validated.
