PM-Handbook For HPUX

1, # BDF
Verify that the file system usage is less than 90%
2, # ioscan-FN-fncdisk-fncprocessor-fnclan
View All Io Devices
3, # lanscan
View Nic running status
4, # ifconfig lanx
Make sure that the network card is configured with the correct address and mask
5, # netstat-Rn
Confirm that the route is configured correctly
6, # swlist
Discover all installed software
7, # swlist-l fileset-a state
Check that all installed file sets are in configured status.
8, # kmtune
All parameters are correctly configured.
9, # ll/STAND /*
Whether the system kernel exists (vmunix, vmunix. Prev, system, system. Prev, ioconfig)
10, dmesg
Check whether information such as SCSI reset and file system full is available.
11, lvlnboot-V
Boot Disk configured
12, vgdisplay-V
Displays the volume group information, including PV and LV. The number of cur PV and act PV does not match, or the number of cur LV and open LV does not match.
13, # lvdisplay <lvname>
Displays the logical volume size, attributes, and status. Status: available/synced. No stale status.
14, # swapinfo-ATM
Displays System Buffer information. The configured local device usage is 0%.
15,/var/tombstones/ts99
No valid timestamp in the file, the file size is the same as other
16, # crontab-l
Displays the specified scheduled job.
17,/var/adm/syslog. Log
No error information
18,/var/adm/rc. Log
No error information
19,/var/adm/shutdownlog
Display correct historical downtime
20, # amdsp-I; amdsp-
Check the array running status
21, # Sar-U T N
Observe the CPU usage. Pay attention to % WIO and % idle. If the value of % WIO is too high, it indicates that the hard disk has an I/O bottleneck. If the value of % idle is high, it indicates that the CPU is idle, if the % idle value is high but the system response is slow, it may be that the CPU is waiting for memory allocation. In this case, the memory capacity should be increased. % If the idle value is lower than 10, the CPU processing capability of the system is relatively low, indicating that the most necessary resource in the system is the CPU
22, # Sar-d t n
Observe the hard disk usage, in the displayed content, the wd-0 is the name of the hard disk, % busy value is relatively small, indicating that the time used to process the transfer request is too small, file System efficiency is not high. In general, the % busy value is higher, the avque value is lower, and the file system efficiency is higher. If the % busy and avque values are relatively high, this indicates that the hard disk transmission speed is too slow and needs to be adjusted.
23, # vmstat
When running the vmstat command without parameters, the values of the AVM (active virtual memory) and free (Free List zise) columns must be concerned first. If the AVM value is large and the free value is small, the system may have a memory bottleneck, we must use the vmstat command with the-s option to check whether deactivation/reactivation activity is happening in the system.
24. Clear the core dump file.
# Find/-name core-exec RM {}/;
Whether there are unnecessary core files
25,/var/adm/crash /*
There should be no kernel unload directory, such as crash.0, crash.1
