Example of a atae blade for the USM management in Linux

USM System is used to manage atae blades, HP pcserver, IBM pcserver, oceanspace program tools, which can achieve the deployment of equipment systems, data backup, equipment maintenance. products will certainly give priority to  own devices, mainly in the case of Atae hosts.

First, remote restart and Kdump dump

In the maintenance process, the host will often encounter no response or hang machine. You can restart and dump Kdump information by following these steps:

1, open the browser input https://USM_IP:18443, use the user name password login, select Maintenance--KVM

2, select the corresponding knife frame and blade slot, you can through the Magic key or send the corresponding function keys to achieve host restart and Kdump dump:

Note:

1, the KVM sends the combination key "ALT + Sysrq+d (SLES9) or" Alt+sysrq+c "(SLES10);

2, generated kdump files, stored in the/home/year-month-day time directory. Collect system Information and analyze kdump information, you can use the LOG_COLLECTOR.TAR.GZ toolkit. After performing the sh atae_log_collector.sh press 3, select the OS System Information collection, the tool will automatically collect the information in the Vmcore file. You can also collect kdump information by using the following command:

Crash/usr/lrsp/kdump/vmlinux Vmcore <<eof
BT >bt.txt
foreach BT >all-bt.txt
Dev >dev.txt
Dev-i >>dev.txt
Dev-p >>dev.txt
Files >files.txt
foreach Files >all-files.txt
IRQ >irq.txt
Kmem-f >pmemory.txt
Kmem-i >memory.txt
Mach >mach.txt
MoD >modules.txt
Mount >mount.txt
NET >network.txt
Net-s >>network.txt
PS >ps.txt
Ps-t >>ps-t.txt
Ps-c >>ps-c.txt
Runq >runq.txt
Sig >sig.txt
Set >set.txt
Swap >swap.txt
Task >task.txt
foreach Task >all-task.txt
Sym-l >sym-l.txt
Sym-m >sym-m.txt
Log >dmesg.txt
SYS >sys.txt
Exit
Eof
3, can also through the SMM Blade management of a single board for the command line restart and Kdump dump, the command is as follows:

Sles9:smmset-l bladen-d sysrq-v D
Sles10:smmset-l bladen-d sysrq-v C

second, the USM rescue repair

1, from the http://support.com website download rescue software source rescue.tar.gz;

2, the Rescue software source rescue.tar.gz Copy to the USM server, for example, stored in/tmp directory;

3. Enter the/tmp directory and execute commands to extract the software source below.

# cd/tmp
# TAR-XVZF Rescue.tar.gz-c/
After successful execution of the command, the rescue software source is decompressed to the/iso directory of the USM server.

Note: The above steps only need to be performed the first time you use it.

4, in the USM "Deployment >> software source management >> production software Source" interface, select Rescue software source, click "Production",

5, select Deployment > Deployment Task Management, click Add, and create a deployment task. Select the rescue mode software source, select the machine box where you want to enter rescue mode, click Next, and select the business board to enter rescue mode. Click Next to display the configuration software source parameter interface. You do not need to configure the software source parameters and click Next. Click Submit Task.

6. Select the rescue deployment task you just created, click Execute, and perform the rescue deployment task.
