RX3660更換SAS硬盤(pán)

1、RX3600更換SAS硬盤(pán)問(wèn)題對(duì)于安月t主機(jī)rx2660,rx3600,rx6600,BL860c,BL870c,在安裝HPUX操作系統(tǒng)的情況下，通常使用的都是HP8InternalPortSASController連接SAS硬盤(pán)。HPUX操作系統(tǒng)識(shí)別到的是通過(guò)SASController劃分后的Lun而非真正的物理硬盤(pán)。HP8InternalPortSASController只提供對(duì)硬盤(pán)RAID1配置，最多支持四塊硬盤(pán)創(chuàng)建RAID1,初始化配置需要進(jìn)入到EFI下進(jìn)行。如果有硬盤(pán)損壞，可以通過(guò)命令觀察RAID狀態(tài)后直接更換解決方案1.因?yàn)槭菍?duì)跟盤(pán)做操作，我們一定在做硬盤(pán)更換前做跟卷備份，這個(gè)過(guò)程
