Removing a control processor blade (CP8)
The SAN384B-2 continues to operate while a CP blade is being installed if the
redundant CP blade is active and a failover does not occur. You can prevent
failover by entering the
haDisable
command.
Attention:
Follow ESD precautions (see “ESD precautions” on page xxi) when
handling any blades.
Complete the following steps to remove a CP8 control blade (CP).
1.
Remove the chassis door. (See “Removing and installing the chassis door” on
page 67.)
2.
Log in to the active CP as the
admin
. You can use a serial cable or Telnet, Web
Tools, or Fabric Manager. Determine which CP is active using the
haShow
command or view the active LED on the front of the CP.
3.
If the faulty CP is the active CP, issue the
haFailover
command. Wait until the
failover has completed. Use the
haShow
command to verify the CPs are
synchronized and the failover is complete.
Depending on the nature of the CP failure, it is possible that the
haFailover
command will not work. Proceed to the next step anyway.
4.
Enter the
haDisable
command. This is required before physically removing and
replacing the CP blades.
5.
Power off the blade you are replacing by sliding the slider switch in the left
ejector to the right, to the off position.
Do not eject the blade until the power LED is off and you have completed the
next two steps.
6.
Disconnect all cables from the faulty (standby) CP blade you are replacing.
7.
Unscrew the thumb screws from both ejectors using the Phillips screwdriver.
8.
Lever open both ejector handles simultaneously to approximately 45 degrees
and pull the CP blade out of the chassis (see Figure 35 on page 77).
