Time Required for Dump Collection

-QuickDump

1.From pressing the NMI switch until the server is started: about 5 minutes

2.From the server startup until the completion of a dump file creation: 10 minutes/1GB of memory

-diskdump

1.From pressing the NMI switch until the completion of collecting dump and the server startup: About 10 minutes (It may take shorter time depending on the mounted memory amount.)

Storing Dump File

- Quick Dump

When there is not enough space for storing the dump file, Quick Dump deletes other dump files and stores the new one.

Note: Save necessary dump files to other storage device in order to avoid the files to be deleted before the storage run out of space.

- diskdump

When there is not enough space for storing the dump file, dump is not collected.

Note: Store necessary dump files on other storage device and make sure there is enough space to store a new dump file.

Notes on Collecting diskdump

-The HDD access LED illuminates during dump collection.

-The screen may remain blank even if dump is being collected. Do not perform forced DC off.

BACKUP OF IPMI INFORMATION

Collect the IPMI information. NEC ESMPRO Agent must be installed to collect the information.

1.Log on to the system as a user with a root authority.

2.Move to the directory where the NEC ESMPRO Agent is installed.

Unless you have specified the installation destination, it is installed in “/opt/nec/esmpro_sa.” In this description, it is assumed to be installed in “/opt/nec/esmpro_sa.”

cd /opt/nec/esmpro_sa

3.Move to the directory where tools are stored. cd bin
