Remove All Enclosures at Once or One at a Time?
Remove All Enclosures at Once or One at a Time?
The two methods of removing enclosures each have advantages and disadvantages.
If you are removing only one enclosure, there is no difference in these methods.
Removing All Enclosures At Once
Procedure
1. Route all applications and processes away from all enclosures to be removed.
2. Delete all the enclosures from the system configuration at once.
3. Remove them physically from the system one at a time, as described in Section 4,
Reducing a System Online.
Advantage
This method allows you to reconfigure your donor system only once, rather than after
each enclosure has been prepared and removed. Therefore, your system preparation
time is significantly reduced.
Disadvantage
This method can increase the difficulty of pinpointing the source of any problems.
Removing Enclosures One at a Time
Procedure
1. Route all applications and processes away from the enclosure to be removed.
2. Delete the enclosure from the system configuration.
3. Remove the enclosure physically from the system.
4. Repeat this procedure for each enclosure to be removed.
Advantage
This method makes it easier to pinpoint the source of any problems.
Disadvantage
System preparation time is increased because you reroute all applications and
processes and reconfigure the donor system one enclosure at a time.
