Key Valid Period
Select a key expiration period that is based on the date when the key from the server is obtained for
the first time (beginning of use).
When the key expires, a new key is obtained from the key server and the expired key is
automatically replaced. If the key expiration period is changed, the same key is used from the first
date of use until the key expired. Note that the "first date" indicates the first day of use instead of
the first day of the key changed.
- Unlimited
The same key is used until exactly 20 years elapses since the key was first used.
- 1 month - 12 month
The same key is used until the date and time in the specified month elapses since the key was
first used. If the same date does not exist in the specified month (such as April 31st), the
expiration date of the key becomes the last date of the specified month.

The same server ID (except for "None") cannot be selected for both the master and slave
servers. Note that "None" cannot be selected for both of the servers when RAID groups are reg-
istered in the key group.
The key can only be updated when the master server is specified. Refer to "11.2.6.9 Update SED

temporality. Select "None" for the target key server before starting maintenance. After
maintenance is complete, set the key server parameters again.
