M03- basic admin
- Alternative GUIs
  - ?哪里可调出windows computer management?(MMC)
- RLM模块
  - 公司的应该看看是否可以配置
- Login
  - Telnet 允许options的试验没成功.
  - RSH - 允许远程机器不用维护console会话(without having console session) 来执行console命令 (一般用的filer的用户是root用户远程用户如果不是root 需要-l option)
    - Options rsh.enable on
    - Configuration file: /etc/hosts.equiv
      - Format: hostname(IP) username(remote user)
    - 客户端命令格式
      - Unix : rsh storage_system "command"
      - Windows: rsh storage_system -l <user> "command" (windows用户一般不可能定义root用户所以-l, jj/Administrator - 一定写成Administrator)
        调试: 可以看日志中的登录信息提示(或者root用户登录console或telnet会话后日志屏显)
  - Ssh
    - Secureadmin
      - Host keys are stored in /etc/sshd/ssh_host_key, /etc/sshd/ssh_host_rsa_key, and /etc/sshd/ssh_host_dsa_key.
      - Then try : permission denied
- Advanced privilege commands
  - Priv set advanced
  - Priv set admin
  - Sample
    - disk命令在adv模式下多了一些命令:
      unfail [-s] <disk_name> - unfail a disk (-s not valid in maintenance mode)

power_cycle [ -f ] { [-d <disk_list>] | [ -c <channel_name> [ -s <shelf_number> ] ] } - power-cycle one or more disks
upgrade_ownership - upgrade disks to new ownership scheme

Basic system configuration
- Sysconfig
  - -v:get system configuration info
  - -r:raid info
  - -d:disk info
  - -c: check configuration whether has some wrong.
- Sample
  - 这次启动的时候filer2遇到点问题:(后来filer1 giveback后看起来问题消失了)

System configuration
- Command line interface
  - Options/vol options
    - Will save in related configuration files automatically
      - File is in /etc/registry---don’t change this file manually!!!
      - 有一些系统自动的备份的registry存在--如/etc/registry.lastgood /etc/registry.bck
        怎样调用呢?
    - Options [name ] values(on|off or other)
      - value如果包含特殊字符(比如包含空格),用"".
      - 可以过滤
    - Vol & aggr options
      - filer1> vol options vol0

root, diskroot, nosnap=off, nosnapdir=off, minra=off,

no_atime_update=on, nvfail=off, ignore_inconsistent=off,

snapmirrored=off, create_ucode=on, convert_ucode=on, maxdirsize=2621,

schedsnapname=ordinal, fs_size_fixed=off, compression=off,

guarantee=volume, svo_enable=off, svo_checksum=off, svo_allow_rman=off,

svo_reject_errors=off, no_i2p=off, fractional_reserve=100, extent=off,

try_first=volume_grow, read_realloc=off, snapshot_clone_dependency=off,

filer1> aggr options aggr0

root, diskroot, nosnap=off, raidtype=raid0, raidsize=8,

ignore_inconsistent=off, snapmirrored=off, resyncsnaptime=60,

fs_size_fixed=off, snapshot_autodelete=on, lost_write_protect=on
Sample:
Aggr options aggr0 raidtype raid4(如果原来是dp)
Disk zero spares-看到多了一个spare盘

Other configuration files
- /etc/hosts; /etc/rc; /etc/hosts.equiv; /etc/dgateways
- 如果配置出线错误,可能filer不能使用甚至启用,此时,可以手工执行一些命令来修正(比如网络如果设置有问题,可以ifconfig手工修改先,网络通了然后再去修改这些配置文件.

Admin hosts
- NFS:
  - 要求:setup命令设置adminhost或者--修改/etc/hosts.equiv来设置授权机器和用户
  - Admin host上获得的权限:以root权限mount filer root directory; 用rsh来远程管理command
- Cifs
  - 要求:domain administrator(如果在域上的话)
  - 访问c$
  - 测试:
    - nfs做过多次了,再做一个与exportfs有没有关系的测试
      /vol/vol0 -sec=sys,ro,rw=192.168.1.220,root=192.168.1.220,nosuid -->修改之后无需等待,直接exportfs看到结果,客户端直接访问(即使先前已经mount了)
      测试过了,root还需要设置 /etc/是root用户拥有的,
    - 用windows试一下修改系统配置文件
    - Filer1>useradmin user list

Name: administrator

Info: Built-in account for administering the filer

Rid: 500

Groups: Administrators

windows客户端上(??任意客户端??)-因为现在的filer cifs的模式为netgroup,没有domain(以后架设一个域来测试一下)
//192.168.1.221/c$ -用filer本地上的administrator登录
展开看到目录树,再去修改--ok
此时,在filer上监控一下

filer1> cifs sessions -s

users

Security Information

192.168.1.6() (FILER1/administrator - root)

user is a member of group daemon (1)

User is also a member of Everyone, Network Users,

Authenticated Users

console上的编辑
- Rdfile & wrfile(个人不推荐用这种方法,因为该工具不方便而且有风险-不注意就清掉了以前的内容)

用filer view来修改-略,图形化的方式,看看就行.
