1. 戴尔服务器iDRAC可以使用 概览-iDRAC设置-设置-时区和NTP 来设置时区和校时；
  2. 戴尔服务器iDRAC可从 概览-服务器-故障排除-SupportAssist-保存收集 来收集Lifecycle日志；
  3. 上一条主要要选择 编辑集合数据 来开启Raid控制器日志；
  4. 收集日志期间，不要关闭、刷新、打开其他标签等，否则会中断日志收集；
  5. 戴尔服务器R630、R730xd需要先将Lifecycle升级到2.41.40版本，然后再升级到2.75.75版本。升级完成之后就可以直接升级BIOS、NIC、SAS等固件了。否则会上传失败；
  6. 命令行设置戴尔服务器时间和时区
# Set NTP settings on a Dell server with iDRAC7
# Set the DNS first to ensure the iDRAC can resolve the NTP host names:
racadm -r 10.1.1.100 -u root -p calvin set idrac.ipv4static.dns1 8.8.8.8
# Set the NTP server names:
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp1 0.asia.pool.ntp.org
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp2 1.asia.pool.ntp.org
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp3 2.asia.pool.ntp.org
# In case it won’t update the time when FQDN’s are used, IP addresses can also be used:
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp1 129.250.35.250
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp2 180.211.88.50
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp3 202.112.29.82
# Enable NTP and set max hops:
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.NTPEnable Enabled
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.NTPMaxDist 16
# Set the timezone:
racadm -r 10.1.1.100 -u root -p calvin set idrac.time.timezone Japan
