HP EVA 4400磁阵 直连的 2台服务器,
服务器HBA卡是AE312A 用的redhat 5.4自带的HBA驱动,
服务器各装了HPDMmultipath-4.4.0聚合软件。安装完软件,没有配置/etc/multipath.conf (HP800说,4.0以上版本已经不需要配置),开启multipath服务。开机自动启动。
聚合之后,
HP800提供的文档上写着 可以fdisk /dev/mapper/mpath* and use them as RAW or FS
但是fdisk /dev/mapper/mpath* 建立400M 主分区时,(建立RAW裸设备)
[root@rac2 ~]# fdisk /dev/mapper/
control VolGroup01-LogVol00
mpath0 mpath1 mpath2 VolGroup01-LogVol01
[root@rac2 ~]# fdisk /dev/mapper/mpath0
The number of cylinders for this disk is set to 71797.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

不知道这是怎么回事?是EVA4400的存储的事情吗?
还有单独对 fdisk /dev/sd* 建立主分区,保存,是不会有错误。
有人知道怎么回事吗
有人做过类似项目吗?可以告诉下吗 |
