Enabling And Disabling Connections - HP StorageWorks SR2122 User Manual

Enabling and Disabling Connections

A SCSI routing instance becomes active, by default, once it is associated with a
Gigabit Ethernet interface to IP hosts. Each target that is added to an instance is
also, by default, enabled. However, no IP hosts can connect or log in to that target
because the target has no access list association. Once you associate an access list
with a target, it is automatically enabled; the IP hosts specified by access list
entries are allowed to connect or log in to the target.
Use the scsirouter target disabled command to control access to the
target without changing the access list association or stopping the entire SCSI
routing instance. Existing connections and logins are not affected, but future
connections and logins are prohibited.
Use the scsirouter target enabled command when you are ready to
allow connections and logins again.
For example, suppose you have a problem with an entry in the access list,
webserver2. This access list is associated with the target, webstorage2, which is,
in turn, associated with the SCSI routing instance foo.
To temporarily disable access to the target associated with a problem access list:
1. enable — Enter Administrator mode.
2. show scsirouter foo stats — Display status to confirm the SCSI
3. show scsirouter foo — Verify the name and current status of the
4. scsirouter foo target webstorage2 disabled — Disable
