IBM support might ask you to collect trace files and dump files from your system
to help them resolve a problem. Typically, you perform this task from the Storwize
V7000 Unified management GUI. You can also collect information from the
Storwize V7000 control enclosure itself.
The control enclosure management GUI and the service assistant have features to
assist you in collecting the required information. The management GUI collects
information from all the components in the system. The service assistant collects
information from a single node canister. When the information that is collected is
packaged together in a single file, the file is called a snap.
Special tools that are only available to the support teams are required to interpret
the contents of the support package. The files are not designed for customer use.
Always follow the instructions that are given by the support team to determine
whether to collect the package by using the management GUI or the service
assistant. Instruction is also given for which package content option is required.
v If you are collecting the package by using the management GUI, select Settings
> Support. Click Download Support Package. Follow the instructions.
v If you are collecting the package by using the service assistant, ensure that the
node that you want to collect logs from is the current node. Select the Collect
Logs option from the navigation. You can collect a support package or copy an
individual file from the node canister. Follow the instructions to collect the
information.
Use this procedure to perform a node rescue.
A failure has indicated that the node software is damaged and must be reinstalled.
Use the service assistant to reinstall the software.
1. Ensure that the node you want to reinstall the software on is the current node.
Go to "Accessing the service assistant" on page 174.
2. Select Reinstall Software from the navigation.
3. Select Rescue from another node.
You can remove and replace from the control enclosure or the expansion enclosure.
Attention: If your system is powered on and performing I/O operations, go to
the management GUI and follow the fix procedures. Performing the replacement
actions without the assistance of the fix procedures can result in loss of data or
access to data.
