SUN系统维护命令大全


  1、查看机型:SUn的小型机的机型都在面板上写着有,如NETRA T 1125,还有比如utra 5,utra 10等等。
  
  2、查看cpu个数 (错误,不正确,因为sun中的top命令不能完全看到所有的cpu情况,与HP用法也不一样)
  #top
  CPU states: 99.3% idle, 0.1% user, 0.6% kernel, 0.0% iowait, 0.0% swap 表示只有一个cpu
  
  正确方法:
  用dmesg |grep cpu
  
  便可以看到正确的 cpu个数了。
  
  3、查看内存
  #dmesg |grep mem
  mem = 2097152K (0x80000000)
  avail mem = 2087739392
  
  4、查看磁盘的个数
  #vxdisk list
  DEVICE TYPE DISK GROUP STATUS
  c0t0d0s2 sliced - - error
  c0t0d0s7 simple c0t0d0s7 rootdg online
  c1t0d0s2 sliced - - online
  c1t1d0s2 sliced smpdg2 smpdg online
  c1t2d0s2 sliced smpdbdg1 smpdbdg online
  c2t0d0s2 sliced - - online
  c2t1d0s2 sliced smpdg1 smpdg online
  c2t2d0s2 sliced smpdbdg2 smpdbdg online
  
  5、如何查看文件系统
  #df -k
  Filesystem kbytes used avail capacity Mounted on
  /dev/dsk/c0t0d0s0 4032142 1050675 2941146 27% /
  /proc 0 0 0 0% /proc
  fd 0 0 0 0% /dev/fd
  /dev/dsk/c0t0d0s6 7304977 29 7231899 1% /home
  /dev/dsk/c0t0d0s5 4032142 402929 3588892 11% /opt
  swap 3418392 32 3418360 1% /tmp
  /vol/dev/dsk/c0t6d0/informix
  201730 201730 0 100% /cdrom/informix
  /dev/vx/dsk/smpdg/smpdg-stat
  1055 9 941 1% /smpwork
  /dev/vx/dsk/smpdg/lv_smp
  17336570 128079 17035126 1% /sms
  
  6、查看卷组、逻辑卷的位置
  #cd /dev/vx/dsk/
  比如smpdg等等都在该目录下了,然后再进入某个卷组目录就可以看到该卷组下面的逻辑卷了。
  
  7、如何创建卷组、逻辑卷、文件系统
  A、创建smpdg逻辑卷组(假设现在是将c1t1d0 和c1t2d0两块物理磁盘来创建smcpdg逻辑卷组)
  vxdisksetup -i c1t1d0 (格式化物理磁盘)
  vxdisksetup -i c2t1d0
  vxdg init smpdg smpdg1=c2t1d0 (将物理磁盘加入到逻辑卷组smpdg)
  vxdg -g smpdg adddisk smpdg2=c1t1d0
  
  然后再来创建逻辑卷、文件系统
  vxassist -g smpdg -U fsgen make lv_smp 17200m layout=nolog smpdg1
  vxassist -g smpdg mirror lv_smp layout=nostripe smpdg2
  newfs -C -f /dev/vx/rdsk/smpdg/lv_smp
  
  假设现在的一台机器上挂接到/sms
  mkdir /sms
  chown smp:smp /sms
  vxvol -g smpdg startall
  mount /dev/vx/dsk/smpdg/lv_smp /sms
  umount /sms
  vxvol -g smpdg stopall
  vxdg deport smpdg
  
  然后再在第二台机器上挂接到/sms
  mkdir /sms
  chown smp:smp /sms
  vxdg import smpdg
  vxvol -g smpdg startall
  newfs -C -f /dev/vx/rdsk/smpdg/lv_smp
  mount /dev/vx/dsk/smpdg/lv_smp /sms
  umount /sms
  
  备注:以上是创建一个共享的文件系统
  往往由于smpdg要分配给某一个应用来使用,所以需要再来创建一个个逻辑机运行时挂接的文件系统:
  vxassist -g smpdg -U fsgen make smpdg-stat 2m layout=nolog smpdg1
  vxassist -g smpdg mirror smpdg-stat layout=nostripe smpdg2
  newfs /dev/vx/rdsk/smpdg/smpdg-stat
  
  B、创建smpdbdg逻辑卷组
  创建卷组:
  vxdisksetup -i c1t2d0
  vxdisksetup -i c2t2d0
  vxdg init smpdbdg smpdbdg1=c1t2d0
  vxdg -g smpdbdg adddisk smpdbdg2=c2t2d0
  vxassist -g smpdbdg -U fsgen make smpdbdg-stat 2m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror smpdbdg-stat layout=nostripe smpdbdg2
  newfs /dev/vx/rdsk/smpdbdg/smpdbdg-stat
  
  创建逻辑卷:
  vxassist -g smpdbdg -U gen make lv_rootdbs 128m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_rootdbs layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_logdbs 300m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_logdbs layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_phydbs 100m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_phydbs layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_tempdbs 1000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_tempdbs layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_svcchunk1 2000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_svcchunk1 layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_svcchunk2 2000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_svcchunk2 layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_svcchunk3 2000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_svcchunk3 layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_recchunk1 2000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_recchunk1 layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_recchunk2 2000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_recchunk2 layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_recchunk3 2000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_recchunk3 layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_recchunk4 2000m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_recchunk4 layout=nostripe smpdbdg2
  vxassist -g smpdbdg -U gen make lv_recchunk5 1700m layout=nolog smpdbdg1
  vxassist -g smpdbdg mirror lv_recchunk5 layout=nostripe smpdbdg2
  
  C、附逻辑卷的属性
  vxedit -g smpdg -v set user=smp group=smp lv_smp
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_rootdbs
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_logdbs
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_phydbs
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_tempdbs
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk1
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk2
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_svcchunk3
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk1
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk2
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk3
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk4
  vxedit -g smpdbdg -v set user=informix group=informix mode=660 lv_recchunk5
  
  备注:在SUN的机器中在给逻辑卷付属性的时候,等于用chown、chmod来作。
  
  8、如何删除卷组
  其实也就是去激活和倒出的过程,然后再来对物理磁盘重新格式化就完了。
  vxvol -g smpdbdg stopall
  vxdg deport smpdbdg
  vxdisksetup -i c1t0d0
  vxdisksetup -i c2t1d0
  ......
  
  这样做了之后就不会再有/dev/vx/smpdbdg目录了。
  
  9、如何建立共享卷组
  在第一台机器上先建立卷组,假设已经建设好卷组smpdg,现在要在第二台机器上建立共享卷组smpdg,则先在的一台机器上将smpdg去激活、并且倒出smpdg:
  smcp01>vxvol -g smpdg stopall
  smcp01>vxdg deport smpdg
  
  再来在第二台机器上激活、导入smpdg:
  smcp02>vxdg import smpdg
  smcp02>vxvol -g smpdg startall
  
  切换后对用以下三个命令进行查看是否切换成功:
  vxdg list //用于查看逻辑卷组的信息
  vxdisk list //用于查物理磁盘的信息
  vxprint -vt //用于查看所有卷的信息
  
  10、如何查看磁盘的大小
  
  方法一:
  #format
  然后选择盘的代号,回车进入下一级菜单,再选inquiry,就得到该盘的大小信
  息,比如:
  Vendor: FUJITSU
  Product: MAN3184M SUN18G
  Revision: 1502
  
  注意:format是一个功能强大的磁盘诊断工具。
  
  方法二:
  #cd /opt/SUNWexplo/bin/
  运行explorer得到磁盘的信息包,是一个目录,进入该目录,就发现有一个disks目录,进入该目录发现有一个diskinfo文件,用如下命令看各个磁盘的大小:
