Truecopy Troubleshooting - Hitachi AMS 2000 Reference Manual

TrueCopy troubleshooting

If the following problem occurs, the pair status is changed to PSUE:
• The path is detached
• A logical abnormal state occurs due to problems with the storage
system
• An abnormal state occurs from causes unrelated to the storage system
If a hardware or Fibre path error occurs while you are operating the
TrueCopy, both of the following are necessary:
• A CCI user intervention
• Assistance from a Hitachi Customer Service representative
For example, when formatting is needed to resolve an LU error and that LU
is used for TrueCopy, the pair must be released by you (CCI operation by
you) before the LU can be formatted. Therefore, please contact Hitachi
personnel because maintenance requires you to issue CCI commands. Note
that the Hitachi personnel can only remove errors which result from
hardware. An operation such as recovering the TrueCopy pair status (for
example, resynchronizing) must be done by you.
