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:     0: rmt/0ln HP C1537A L706 62######## <
