【正文】 如果您在同一個 target 上有多個 LUN，您必須手動更改配置文件/kernel/drv/。在驅(qū)動程序安裝后，此文件將自動加載 target0至target17的 LUN0，如果您有大于 17的 Target或者同一個 target有多個LUN，必須手工將其他 Taget和 LUN加進配置文件。 3) 如果同一臺主機裝有兩塊以上的 LightPulse HBA，并且需要啟用其 IP 功能，您必須為除第一塊外的每一塊 HBA 手工建立一個地址文件。驅(qū)動安裝過程只自動為第一塊 HBA 建立地址文件： /etc/ 。h) 重啟系統(tǒng) sync reboot. 關(guān)于/kernel/drv/ 的修改 The following discussion applies only when you have enabled FCP functionality in lpfc.Solaris target drivers must be instructed which disks to probe for at boot time. These instructions are contained in a configuration file specific to each target driver. On SPARC the disk target driver is called sd。 on x86, the disk target driver is called sd for Solaris 7 and cmdk for Solaris . The configuration files are, respectively, and and are usually found in /kernel/drv. There will only be one of these two target drivers on your system. See the (4) man page for additional details. The tape target driver is called , and entries must be included in this file in order to run tape devices.Each disk drive on the Fibre Channel must have an entry in or . The system administrator may have to define additional targets and LUNs in these files. For FCP there can be up to 512 targets, with a maximum of 256 Logical Unit Numbers (LUN) per target. Initially, the or file has entries of the format:name=sd class=scsi target=0 lun=0。We use the class keyword to ensure that Solaris specifically probes all adapters controlled by all drivers, that register themselves as class=scsi, for the specified targets and LUNs. The lpfc driver registers itself as class=scsiThe installation procedure for lpfc automatically updates or to search for Fibre Channel disk drives. The instructions added to the configuration file look like this: 7name=sd parent=lpfc target=0 lun=0。(On x86, Solaris , you will see name=cmdk.)One such line is added for the first 18 targets, ., targets 0 through 17. We do not automatically add a line for every possible LUN. Instead, we only search the first 18 targets for devices at LUN 0. No entries are automatically added to the file.If you want to use disks (., RAID arrays) with nonzero LUNs, or more than 18 targets, simply add lines to the target driver configuration file specifying the desired target ID and LUN(s). For instance, we have already included this example in your target driver configuration file:name=sd parent=lpfc target=17 lun=0。name=sd parent=lpfc target=17 lun=1。name=sd parent=lpfc target=17 lun=2。name=sd parent=lpfc target=17 lun=3。(On x86, Solaris , you will see name=cmdk.)We use the parent keyword to ensure that Solaris specifically probes all adapters controlled by the lpfc driver for the specified targets and LUNs.Note that changes to a target driver39。s configuration file will only take effect after the system has been rebooted.？1） 進入 PROM的方法：當系統(tǒng)激活時，同時按下STOP鍵和a鍵,這時系統(tǒng)出現(xiàn)提示符 ok，即表明系統(tǒng)當前處于 PROM監(jiān)控等級2） 在 PROM狀態(tài)提示符下確認當前系統(tǒng)所連接的 SCSI設(shè)備狀況： ok probescsiall 這時,系統(tǒng)將顯示所能識別的 SCSI設(shè)備極其設(shè)備號(Target ID)和邏輯單元號（Unit 或 Lun） 。 3） 記下屏幕上的 output。進入系統(tǒng)后修改 。關(guān)于修改方法這里簡單舉例說一下：例：你的系統(tǒng)連接了兩臺陣列，知道其配置為陣列 1： Target 0，Lun0 （CxT0D0） Target 0，Lun1 （CxT0D1）Target 0，Lun2 （CxT0D2）Target 0，Lun3 （CxT0D3）Target 0，Lun4 （CxT0D4） 8陣列 2：Target 24，Lun0 （CxT24D0）Target 25，Lun0 （CxT25D0）Target 26，Lun0 （CxT26D0）Target 27，Lun0 （CxT27D0）因為 Emulex驅(qū)動程序在安裝時只對 Target017，Lun 為 0的設(shè)備自動加載，需要在修改/kernel/drv/。在 Emulex自動生成的字段中間（務(wù)必加在中間，否則卸栽驅(qū)動程序時不會自動將您加入的行刪除）加入。name=sd parent=lpfc target=0 lun=1。name=sd parent=lpfc target=0 lun=2。name=sd parent=lpfc target=0 lun=3。name=sd parent=lpfc targe
