5. Note for installing and repairing the mirroring kit
When installing or repairing the mirroring kit, fully understand the following descriptions to avoid erroneous handling and procedures. When a
HDD which has once been used for the mirroring kit is reused without proper preparation, it may cause an error and destruction of user data, or
other troubles.
HDD which has once been used for the mirroring kit is reused without proper preparation, it may cause an error and destruction of user data, or
other troubles.
The following three cases must be strictly avoided.
• When newly installing a mirroring kit, do not use one which has been once used.
• When replacing the HDD because of a HDD trouble, do not replace it with a HDD which has been once used in a mirroring kit.
• When replacing the HDD because of a HDD trouble in the machine, do not replace it with a HDD which has been once used in a mirroring kit.
NOTE: When a HDD is once used in a mirroring kit, the mirroring information is written into the HDD. This causes a trouble by erroneous
using.
The details of inhibited items, results of erroneous procedures, and precautions for avoiding those errors are described below.
A. Details of inhibited items

When newly installing a mirroring kit, do not use one which has been once used.
Trouble contents
If HDD2 which has been once used is used for new installation of a mirroring kit, the data in HDD2 will be written into HDD1. This causes era-
sion of the original user data, freeze of the machine, or other troubles. The "HDD which has been once used" includes a HDD which was just
installed and conducted only.

Trouble contents
E7-A5 error occurs. If a HDD which has been used in a mirroring kit is used as the machine HDD, the machine does not operate normally.
In this case, the trouble of erasing the original data is avoided.
Countermeasures

tion. (For details, refer to "5-C. Deleting the HDD mirroring information.")
When a HDD is used without any other HDD, the mirroring information must be erased before executing SIM62-1 to format.
This procedure allows the HDD being treated as a new HDD.
When removing the HDD after installation of the mirroring kit, remove both HDD's simultaneously. If only one HDD is removed and then
installed again, the data of both HDD's may not match, causing a trouble.
