用arcconf在线创建StorageTek Raid Controller镜像/Make live mirror with arcconf for StorageTek RAID Controller

X4170 with StorageTek raid controller, 做系统的时候为了节省成本没有做镜像,以至于后来硬盘问题频发导致多次系统crash。让我想到必须做镜像和raid了。研究了下StorMan的手册,发现可以用GUI的StorMan来配置,也可以用arcconf来配置,我没有图形界面,所以只好用arcconf了。

X4170 with StorageTek raid controller has no mirror due to the budget limitation and this caused the OS crash many times by disk failure. This forces me to make mirror for OS. According to the manual of StorMan, this can be done by GUI or arcconf. I have no GUI so I must use arcconf.

It’s easy. At least you need to have a free disk. I assume my OS disk is 0,0 and free disk is 0,1. The live creation command should be:

bash-3.2# arcconf modify 1 from 0 to max 1 0 0 0 1
Controllers found: 1
The requested modification does not support change of logical device size.
The target logical device must be 285696 MB

//I would like to use max as the volume size but the command says the size must be 285696

Command aborted.

bash-3.2# arcconf modify 1 from 0 to 285696 1 0 0 0 1
Controllers found: 1
Reconfiguration of a logical device is a long process. Are you sure you want to continue?
Press y, then ENTER to continue or press ENTER to abort: y

Reconfiguring logical device: os

Command completed successfully.

//It says the process is long but actually it takes less than 1 second.

当然,如果你使用的是新disk,需要首先initialize, 否则会出错://If you’re using a new inserted disk, please initialize first. Otherwise you’ll get aborted

bash-3.2# arcconf modify 1 from 0 to 285696 1 0 0 0 1
Controllers found: 1
Not enough available space.
Not enough available space.

Command aborted.

bash-3.2# arcconf task start 1 device 0 1 initialize
Controllers found: 1
Initializing Channel 0, Device 1.

Command completed successfully.

bash-3.2# arcconf getconfig 1

命令格式/Command format:

arcconf modify <controller> from <logical_volume> to <volume_size> <raid_level> <disk1 IDs> <disk2 IDs>

Or for a more verbose explanation:

arcconf (the raid utility)

modify (modify an existing raid)

1 (the controller with your simple_volume you want to turn into a raid 1)

from 0 (the logical volume you want to convert into a raid 1)

to 139900 (the size of the volume. In my version of arcconf, this had to be set to a numeric value matching the current simple_volume size, and MAX was not a valid option)

1 (the raid level you want to convert to)

0 0 (the first disk ID (0,0) in the raid 1. This should be your existing disk containing the simple_volume that you want to convert to raid 1)

0 1 (the extra available disk ID (0,1) that you are adding to the raid 1 to make it a mirror)

3PAR 7200 setup and installation

Setup Procedure:

1. Physically cable the 3PAR, connect the mgt ports
2. Have a ESXi server in the same subnet, use Virtual Service Processor’s VOF template to deploy the VSP
3. In the console of VSP, use setupusr with blank password to setup the VSP IP
4. Use the SmartStart to connect to VSP to configure VSP and storage
5. Install management console to connect to storage for management

Change IP address of 7200

1. ssh to 3par 7200 storage with user 3paradm
2. setnet startaddr <old-IP> <new-IP> <new-subnet-mask>
3. setnet startgateway / setnet cleargateway
4. Now the storage listen to both new IP addresses and old address, try to ssh to new IP address to verify your IP
5. shownet will see the new IP verified, use ‘setnet finish’ to finish the configuration

X4170 with STK RAID controller 更换root disk

X4170,带STK RAID controller,两块硬盘,一块根盘一块数据,都是做了simple volume,根盘发现坏块,还好只是/export/home,保修,Oracle寄来一块硬盘,更换root disk。以下是几点提要:

1. 下载Sun StorageTek* RAID Manager for x86 Solaris* 10

2. 安装后获取information

arcconf getversion
arcconf getconfig $CNUM
arcconf getstatus $CNUM
arcconf getlogs $CNUM uart
arcconf getlogs $CNUM device
arcconf getlogs $CNUM dead
arcconf getlogs $CNUM event
arcconf getlogs $CNUM event tabular

3. 添加new disk,热插拔,然后在arcconf getconfig里可以看到硬盘

Device #7
Device is a Hard drive
State : Ready
Supported : Yes
Transfer Speed : SAS 3.0 Gb/s
Reported Channel,Device : 0,7 —————————-> so you need to note this information
Reported Location : Enclosure 1, Slot 7
Reported ESD : 2,1
Vendor : SEAGATE
Model : ST914603SSUN146G
Firmware : 0B70
Serial number : 00112083G17Q 6SD3G17Q
World-wide name : 5000C5003AAD501C
Size : 140009 MB
Write Cache : Unknown
FRU : None
S.M.A.R.T. : No

4. 使用new disk创建新volume

# arcconf create 1 logicaldrive max volume 0 7 noprompt
# arcconf CREATE 1 LOGICALDRIVE NAME Data-2 max Simple_volume 0,2

“1″ means controller #; “0 7″ means “Reported Channel,Device” in the “arcconf getconfig 1″,
By default, once new disk inserted ,you just need to run one command “arcconf create” to generate one new disk

# devfsadm -vCc disk //this commands is not mandatory

5. 分区,创建文件系统,然后把现有系统dump到新硬盘上,比如/var

mount /dev/dsk/c0t2d0s3 /a
cd /a
ufsdump 0f – /dev/rdsk/c0t0d0s3 | ufsrestore rvf –

# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t0d0s0

也记录一下,如果需要编辑bootenv.rc时,setprob bootpath的内容应该是format看到的硬盘信息,例如:/pci@0,0/pci-ide@1f,2/ide@0/cmdk@0,0:a,a表示分区0

6. 重新启动,按提示按ctrl+A进入adaptec控制器utility,在manage volume里看到新建的卷,光标移上去按 ctrl+b设置为启动卷,此时可以看到volume的list顺序发生了改变,这个bootable的volume成了1st

7. 所以其实然后只要启动就好,然后可以在系统里删除logic drive

arcconf delete logictdrive 2

Solaris 10 8/11 doesn’t support Broadcom 5720 Dual-Port NIC of R420

Solaris 10 8/11 Doesn’t support broadcom 5720 dual-port NIC

Solution: Install driver manually
Use usb or CD upload the file into the system. Unpack it and run:

# rem_drv bge (remove old bge driver)
# pkgadd -d BRCMbge-Solaris_10u10-i386-15.2.2.pkg
# devfsadm

And you can find the bge in /dev

5720 is in the HCL of Solaris 11
