DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
HDS Product Training on CHA replacement and SVP operation.
TIME ESTIMATE: 20 Minutes
FIELD ENGINEER INSTRUCTIONS
PROBLEM OVERVIEW:
- Processor blocking
- CHKX threshold over
CONFIRM THE FAULT BY CHECKING:
Verify through SIM Log and BY using Maintenance Mode of SVP .
WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
It Is very important that the Hosts Multipathing software be verified as working before the procedure is started. The CHA PCB is the hosts interface connection to the frame . When the CHA PCB is off-lined , access to the LDEV will be lost if alternate paths to the LDEV are not configured and working correctly through alternate CHA PCB's .
It is also not recommended to perform this procedure during a period of heavy I/O .
WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
- Customer verify that mulitpathing works on Hosts accessing the Frame
- Enter maintenance mode in SVP
- Select failing component and initiate replacement
- Replace CHA
- Continue SVP recovery process
- Complete Sim
CONFIRM THE FIX BY:
Verify through the maintenance mode on the SVP , Verify that the customer has access to CHA ports.
OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Verify that the host in use have access to the Ldev through All Paths .
PARTS NOTE:
<special notes regarding parts>
ADDITIONAL COMMENTS:
Replacement procedure is RCH1 for all arrays except 9985 , which uses
RMX1 for MIX PCB in addition to RCH1 .
The documents referenced below can be found on site on the array microcode CD.
