838.0. "C_SWAP Utility: State of the Art" by ROMTSS::MORRONE () Mon Apr 07 1997 11:48

 Hi all,

 Because of the recent confusion I observed within the Field about the
 "C_SWAP utility procedure", I'm trying to summarize the State of the
 Art on his functionality across all most used versions; in other words,
 I would please have an official answer to the following question:

 " Within a redundant HSJ40/HSZ40/HSD30 configuration running HSOF
   version 2.5 or 2.7 or 3.0, which is the official procedure a Field
   engineer should use to replace any faulty module (controller, cache)
   or battery from one of the two running controller ? "

 Even this question may seem repetitive I can assure you it will save
 a lot of time avoiding a very bad service to our Customers.
 Your answers will be used to definitely create a master document on the
 above subject that will be sent across Italy.
 
 Thanks indeed in advance,  Maurizio

    the procedure in the v30 service guide lists those procedures.
    
    With one exception,the procedure assumes that both controllers are
    up and running.  If one of the controllers is down, the
    
    command in the procedure " set this preferred_id=xxx" will fail.
    
    If one of the controllers is down, then on the surviving controlller
    issue a "set nofailover" command before entering the 
    
    "set this preferred_id" command.
    
    Then use the c_swap procedure as shown in the service guide.
838.2C_SWAP procedure unified ??ROMTSS::MORRONETue Apr 08 1997 07:0521
 Tom,

 Do you mean the procedures described within "HSOF v3.0 Service Guide"
 are applicable to HSOF versions v2.5 and v2.7 as well?

 It seems also the service guide doesn't report what actions to perform
 in case I need to stop one controller (within a redundant configuration)
 which has still control over Raidset or Mirrorset (most common example:
 Low or Failed Battery) 

 Thanks again, Maurizio

 P.S.: The 'service guide' (page 76) states:
	"When you use C_SWAP to replace a controller in a SW500 and SW800
	 cabinet, you must have two power supplies; in an SW300 cabinet,
	 you must have five power supplies."

      The above statement is only to say (in dual-redundant configuration)
      I must have redundant power supplies within the controllers shelf in
      order to successfully use the C_SWAP procedure ?
