  Description:
    This command displays iterative channel counters for each head and zone.

    Error 100C DETSEC 00008000
    - this error is caused by the error stats log being not initialized.
    Hit ctl-W to initialize the error log.

  Related Commands:
    any level Ctl-W - enables RW statistics gathering and zeros out the error counters
    level L i   - L>iFFFD will zero out the error counters.
    level L E   - L>E,,0 will disable statistics gathering
                - L>E,,1 will enable statistics gathering
                - L>E,,2 will zero out the error counters

       Where XX..XX is the counter value as follows:
    
       Sectors:    SECTOR BASED      Records number of sectors 
transferred during reads. Note that this
                                     excludes retries and read failures.
    
       HardEr:     SECTOR BASED      Records errors that could not be 
read.  This counter increments
                                     by one per set of retries.
    
       Firm Er:    SECTOR BASED      Records successful reads that 
required one or more retries when system
                                     configured for full error recovery.
  This counter increments by one per
                                     set of retries.
    
       Soft Er:    SECTOR BASED      Records successful reads that 
required one or more retries when system
                                     not configured for full error 
recovery.  This counter increments by
                                     one per set of retries.
    
       Iters:      CODEWORD BASED    Iterations: The number of 
iterations the channel used to find a solution.
                                     Each codeword requires at least one
 iteration.
    
       WSectors:   SECTOR BASED      Records number of sectors 
transferred during writes. Note that this
                                     excludes retries and write 
failures.
    
       WHard:      SECTOR BASED      Write hard errors.  This counter 
increments by one each time
                                     the drive fails to write a sector. 
 This counter only
                                     increments once per set of retries.
    
       WSoft:      SECTOR BASED      Records writes the required one or 
more retries to succeed.
    
       Codewords:  CODEWORD BASED    Number of codewords read from 
media.  Note
                                     that codewords are not sectors. A 
codeword is a unit
                                     of user data and correction 
information.  A 4x1K
                                     drive might have four codewords per
 sector.
    
       BadB:       BIT BASED         Number of bits reported in error 
before correction.
    
       LowLLR:     BIT BASED         Number of bits reported by channel 
having their Logarithmic
                                     Likelihood Ratio below the 
threshold.
    
       syn:        SECTOR BASED      Sync errors: The number of sync 
failures.
    
       era:                          Erasures: Number of erasures 
reported by the channel.
    
       non:        CODEWORD BASED    Noncovergent codewords: Number of 
nonconvergent codewords read
                                     from media.
    
    BIT BASED      means the value is related to the number of bits 
transferred.
    
    SECTOR BASED   means the value is related to the number of user data
 sectors transferrred.
    
    CODEWORD BASED means the value is related to the number of codewords
 transferred.  Note
                   that a single user sector may have several codewords.
