LIBRARY: sysback recovery of sp nodes from CWS through network
==================================================================
HOW TO BACKUP AND RESTORE SP NODES FOR REINSTALLATION WITH SYSBACK
==================================================================
Doc extraction and merge by Josh Davis using multiple sources and
much original data. This information is correct to the best of my
knowledge, but has not been hands-on verified, and as such, neither
I nor IBM may he held liable for this information or any damage
that may or may not result as a direct result of its use.
NOTE: Where available, screen shots have been provided; however,
not all sections have this level of detail.
I. How to set up the CWS for sysback reinstallation of your nodes:
A. Check the filesets on the boot server (CWS)
B. Install proper filesets for device support. See cloning
faxes if exact fileset list is required.
1. Thin node is RS6k/UP (390 equiv)
2. Wide node is RS6k/UP (590 equiv)
3. High node is RS6k/MP (r50 equiv)
4. Silver thin is CHRP/MP (H50 equiv)
5. Silver wide is CHRP/MP (H50 equiv w/ more slots)
C. Reboot CWS to incorporate these changes into the running config.
D. Rebuild sysback boot images
1. `smitty sysback`
2. Configuration Options
3. Network Boot Configuration
4. Add or Change a network Boot Client
1. Fill in the hostname
2. Fill in the Platform type
a. Thin = rs6k (not MP)
b. Wide = rs6k (not MP)
c. High = rs6k/MP
d. Silver = chrp/MP (not rspc)
(NOTE!!! THIS IS NOT RSPC AND MUST BE CHRP/MP OR BOOT
WILL FAIL WITH LED E1F7 INDICATING INVALID BOOT IMAGE!)
5. Update Network Boot Image
1. Select Platform and network type
E. Configure the CWS for a sysback backup/recovery server:
1. `smitty sysback`
2. Configuration Options
3. Remote Services
4. Server Options
5. Configure Remote Services
6. Add or Change a Client
a. Client Hostname (per reverse name resolution)
b. User Access (root, all or specify a user's name)
c. At the menu, fill in the tape devices if apply:
(all, /dev/rmtX or blank for none)
d. Fill in the directories if applicable.
II. Configure and backup your node for possible recovery from CWS
A. Make sure the node is set-up to backup to the CWS
1. `smitty sysback`
2. Configuration Options
3. Remote Services
4. Client Options
5. Configure Remote Services
6. Add or Change a server
a. enter the CWS's hostname per forward name
resolution.
b. Disk options should be No for tape and Yes for
disk (directories).
B. Back up node on a regular basis (From Smit)
1. `smitty sysback`
2. Backup and Recovery Options
3. Full system Backup (Install Image)
4. Back Up the System
5. Choose remote device for backup
6. Select any additional (non rootvg) volume groups to
be included.
C. Back up the node on a regular basis (from command line/script)
1. sysback -l rmtX -h $cws -N $net -T $cpu -k $krn vg1 vg2
a. $cws is the hostname of the cws
b. $net is one of "tok", "eth" or "fddi"
c. $cpu is "rs6k" for all black nodes,
and "chrp" for all silver nodes.
d. $krn is "up" for thin and wide nodes,
or "mp" for high or silver nodes"
e. "vg1 vg2" is a list of all additional vg's to
include other than rootvg which is always
included.
III. How to recover SP2 node given the above setup:
A. spmon -g
B. Power down node
1. Use the gui or issue the command:
2. spmon -p off node1
C. Netboot
1. Global Controls
2. Netboot
3. Select Node Number
D. If netboot fails, or
If you need to boot from a node rather than CWS
1. Open a tty.
a. With the GUI
1. Display Layouts
2. Display Node Layout
3. Node Front Panel
4. Open a TTY
b. Or use: spmon -open node1
2. See appendix for manual netboot process
E. Sysback will come up
1. Change installation Device
2. Select tape on CWS
3. Change Volume Group & Logical Volume Info
4. Verify information
5. Install the System with Current Settings
