求助:Oracle T3-1控制台不识别硬盘 [复制链接]

发表于 2013-07-19 09:53 |显示全部楼层
T3-1主机1号机掉电后再开机发现不识别硬盘,将另一台T3-1主机2号机的盘笼换上1号机后显现相同的故障,就是不认硬盘,然后再把2号机的盘笼装回2号机上,2号机也不识别硬盘了。有没有人遇到类似的问题? 求解。

另:1号机主机系统检测正常,挂接外置硬盘后可启动系统,但盘笼上内置光驱不能启动光盘了,光驱旁边的USB接口正常,可连接外置光驱工作。

直接换硬盘不方便么?有日志么?

信息太少了,是怎么不能识别硬盘,是说boot disk启动不了提示找不到硬盘?还是OK监控模式下probe-scsi-all不能探测到硬盘?
猜测,可能是T3-1做的硬RAID,掉电后导致主板RAID控制器上的部分信息错乱,不能识别硬RAID,你换了硬盘背板,导致硬盘路径更改,也有可能导致主板RAID控制器上的部分信息错乱,所以你2号机也不能识别硬盘了。

probe-scsi-all探测不到硬盘,然后又多插了几块新的硬盘,同样也探测不到新硬盘,然后用sas线和外接稳压电源直接把硬盘连接到主板上,则可以启动solaris10系统了,把硬盘插再回到盘笼,又照样检测不到硬盘。真是有点奇怪,为什么不认盘笼呢

请教怎么样复位硬盘路径?

说了只是猜测,probe-scsi-all探测不到任何的硬盘,那就不是RAID的事情了,下面的帖子里不是有说5220换了个风扇侧板好了吗,也有可能的。

帖子里不是写了吗,2台t5220逐一更换备件测试,换了个风扇侧板好了。
这种比较妖的事情,只能使用替换法尝试了,你那里不是刚好有两台T3-1吗。

或者看看是不是以下问题

Solution
        The physical disks connected to 8-Port 6Gbps SAS-2 RAID HBA need to be configured.
       

Available pcli commands
        Steps to create a single logical drive
Applies to:

SPARC T3-1 - Version All Versions and later
Sun Storage 6Gb SAS PCIe HBA, 8 Port - Version Not Applicable and later
SPARC T3-2 - Version All Versions and later
SPARC T4-1 - Version All Versions and later
SPARC T4-2 - Version All Versions and later
Oracle Solaris on SPARC (64-bit)
Symptoms

Common Symptoms are:

- Cannot see any or more than one disk in "# format" or "ok> probe-scsi-all" although more than one physical disk is installed
- No error messages are generated by the Operating System and "probe-scsi-all"
- OBP command "ok> show-disks" displays path to disks with "LSI,mrsas" in it, example:

/pci@400/pci@2/pci@0/pci@c/LSI,mrsas@0/disk


Cause

SPARC T3/T4 Systems may come configured with internal Disk Backplane connected to a 8-Port 6Gbps SAS-2 RAID HBA (Niwot).
This HBA does not present connected physical disks to the Operation System.
Sometimes one LUN with Preinstalled Solaris image is configured and visible but the remaining internal disks are not.
The physical disks need to be configured in order for the Operating System and "probe-scsi-all" to see them.

Solution

The physical disks connected to 8-Port 6Gbps SAS-2 RAID HBA need to be configured.

1) If a running Solaris instance is available, go to LSI Support Webpage http://www.lsi.com/sep/Pages/oracle/sg_x_sas6-r-int-z.aspx to download Software required to operate the 8-Port 6Gbps SAS-2 RAID HBA. The HBA may be operated in CLI mode with MegaCLI or in GUI mode with MegaRAID Storage Manager.
    Please refer to the Software User Guide available on the page for more information.

2) If there is no Solaris instance on the Server - or the disks need to be reconfigured before reinstallation of the OS - the disks can be configured using the PreBoot CLI (pcli) at OBP.

- use the show-disks command to identify the path to the 8-Port 6Gbps SAS-2 RAID HBA



{0} ok show-disks
a) /pci@400/pci@2/pci@0/pci@f/pci@0/usb@0,2/hub@2/hub@3/storage@2/disk

b) /pci@400/pci@2/pci@0/pci@c/LSI,mrsas@0/disk

c) /pci@400/pci@2/pci@0/pci@8/lpfc@0,1/sd
d) /pci@400/pci@2/pci@0/pci@8/lpfc@0/sd
e) /pci@400/pci@2/pci@0/pci@4/scsi@0/disk
f) /pci@400/pci@1/pci@0/pci@6/lpfc@0,1/sd
g) /pci@400/pci@1/pci@0/pci@6/lpfc@0/sd
h) /pci@400/pci@1/pci@0/pci@4/scsi@0/disk
i) /iscsi-hba/disk
q) NO SELECTION

Steps to create a single logical drive

- type cli -PdList to identify Enclosure Device ID and physical drives

Example:

{0} ok cli -PdList

Adapter #0

Enclosure Device ID: 252
Slot Number: 0
Enclosure position: 0
Device Id: 8
Sequence Number: 2
Media Error Count: 0
Other Error Count: 0
Predictive Failure Count: 0
Last Predictive Failure Event Seq Number: 0
PD Type: SAS
Raw Size: 279.396 GB [0x22ecb25c Sectors]
... output omitted...

- type cli -CfgLdAdd -r0[252:0]

This will create a single disk LUN ( -r0 for RAID 0, with Enclosure #252 physical disk Slot 0 ).

- to display Information about the newly created LUN, type cli -LdInfo -L0

Example:

{0} ok cli -LdInfo -L0

Adapter 0 -- Virtual Drive Information:
Virtual Drive: 0 (Target Id: 0)
Name                :
RAID Level          : Primary-0, Secondary-0, RAID Level Qualifier-0
Size                : 278.464 GB
State               : Optimal
Strip Size          : 64 KB
Number Of Drives    : 1
Span Depth          : 1
... output omitted...


- type unselect-dev when you are finished configuring LUNs

{0} ok unselect-dev


- type the OBP command probe-scsi-all to verify that the newly created LUN is visible in OBP

{0} ok probe-scsi-all

...output omitted...


/pci@400/pci@1/pci@0/pci@8/LSI,mrsas@0
Target 0
  Unit 0   Disk     LSIMR9261-8i2.12    1169920000 Blocks, 598 GB
Target 1
  Unit 0   Disk     LSIMR9261-8i2.12    3509760000 Blocks, 1796 GB


- an existing Solaris instance might need to be reconfigured (e.g. with command devfsadm) to display the newly created LUN in format

上面的例子和我的情况不一样,上面的那个用的是硬raid卡LSI MegaRAID SAS 9261-8i,所以在ok状态下可以使用cli -PdList,而我的就不行。
