The
syslog
file indicates battery refresh operation in progress. Use the
refresh -
s
command to view an active refresh operation. Refer to the Sun StorEdge T3 and T3+
Array Administrator’s Guide for more information on this command. Refresh cycle
time is controlled by the array’s
/etc/schd.conf file
. For example:
You can tune the
/etc/schd.conf
file to specify the interval between battery
refresh cycles and initiate a refresh on a particular day. To specify beginning a
battery refresh cycles at a particular time, edit the BAT_BEG MM-DD-YYYY,hh-mm-
ss value in the
/etc/schd.conf
file. Where:
■
MM is the month number (January = 1)
■
DD is the day number
■
YYYY is the year
■
hh is the hour using a 24 hour clock (6pm = 18)
■
mm is the minute
■
ss is the second (this element is optional)
Caution –
The battery service life dependents on a battery refresh cycle of 14 days.
Altering this time span can decrease battery life.
For example, specify that a battery refresh cycle begin on January 15, 2001 at 11 p.m.,
the entry in the
/etc/schd.conf
file:
Note that the next refresh start time is always calculated from the start time of the
previous refresh cycle. If a user manually starts a refresh cycle, then the next refresh
depends on the starting time of the manually activated refresh cycle.
Note –
If a controller failover occurs, the scheduler daemon starts and behave as it
does during a normal system boot. The scheduler reads the
schd.log
file, and
based on
schd.conf
file, begins the next refresh process. If during the discharge
period (10 to 12 minutes) or recharge period (10 to 12 hours) a controller failover
occurs, the current refresh process is killed and the next refresh cycle starts at the
scheduled refresh time based on the
schd.conf
file. Consequently, the refresh
cycles begins as scheduled previously.
The battery service life is 2 years. When the battery approaches its end of life,
warning messages are sent to the
syslog
file. The first message is sent 45 days
before the end of life, followed by a warning message every five days thereafter. The
