IJ33003: SLOT MAPPING REPORTS WRONG LOCATION CODES

APAR status

• Closed as program error.

Error description

• While using Spectrum Scale Erasure Code Edition
  running on LSI MegaRaid adapters, if the slotmap.yaml
  file is edited directly several unintended consequences can
  arise that would not show up when using the drive mapping
  utility. This can include allowing several disallowed
  characters such as the hyphen in the location code name.
  

Local fix

• Avoid using leading "0" when creating slot location codes.
  After editing a slotmap.yaml file,
  run tslsenclslot.lmr --check-slot-map
  to verify the mapped location codes are valid and
  have the expected form.
  

Problem summary

• While using Spectrum Scale Erasure Code Edition
  running on LSI MegaRaid adapters, if the slotmap.yaml
  file is edited directly several unintended consequences can
  arise that would not show up when using the drive mapping
  utility. This can include allowing several disallowed
  characters such as the hyphen in the location code name.
  

Problem conclusion

• Benefits of the solution:
  Checks have been added to make sure only alphanumeric
  characters are used when mapping location codes for slots.
  This should reduce the chances of an inappropriate slot location
  name. Care must still be taken when using numeric location codes
  with a leading "0," such as 017. These will be interpreted as
  if they were Octal (base 8) numbers.
  
  Work Around:
  Avoid using leading "0" when creating slot location codes.
  After editing a slotmap.yaml file,
  run tslsenclslot.lmr --check-slot-map
  to verify the mapped location codes are valid and
  have the expected form.
  
  Problem trigger:
  Users which edit the slotmap.yaml file on
  LSI MegaRAID systems may be affected.
