HP XP P9500 Storage - Manual (Page 93)

Case 2: When tier relocation is performed with the first collection of monitoring information,
the second collection of monitoring information can be performed. However, the third collection
cannot be started. Because only two fields are used store collected monitoring information,
the third collection cannot be overwritten.
In that case, the third collection of the monitoring information is started after the first tier
relocation is stopped or tier relocation has completed.
The collection of the monitoring information is not started under these conditions as well:
◦ When the second tier relocation is performed, the fourth collection of monitoring
information cannot be started.
◦ When the third tier relocation is performed, the fifth collection of monitoring information
cannot be started.
If such conditions exist, two cycles of monitoring information cannot be collected continuously
while tier relocation is performed.
