通常服务器本机自带磁盘空间有限，都需要额外加载磁盘，可以采用mount方式把远程的共享存储磁盘加载进来，目前用过的有iscsi、ntfs、nfs三种类型一，mount挂载iscsi类型1，查找下准备挂载的磁盘或者存储器[root@localhost /]# iscsiadm -m discovery -t st -p 1x.xx.0.22:32601x.xx.0.22:3260,1 iqn.2001-05.com.equallogic:0-8a0906-6dac38009-c1b1cac2d434efec-pddata1x.xx.0.22:3260,1 iqn.2001-05.com.equallogic:0-8a0906-4061f7f09-29d248cfaed54b9d-daxxxx[root@localhost /]#[root@localhost ~]# iscsiadm -m iqn.2001-05.com.equallogic:0-8a0906-4061f7f09-29d248cfaed54b9d-daxxxx -T /daxxxx -p 1x.xx.0.22:3260 -lTry `iscsiadm --help' for more information.[root@localhost ~]# iscsiadm --helpiscsiadm -m discoverydb [ -hV ] [ -d debug_level ] [-P printlevel] [ -t type -p ip:port -I ifaceN ...
