Understanding interim fix states
The emgr command maintains a state for each installed interim fix.
The following installed interim fix states are maintained
by the emgr command:
- S=STABLE
- The interim fix was installed with a standard installation (-e flag), and successfully completed the last installation operation. To verify the interim fix details, run a check operation on the given interim fix or interim fixes.
- M=MOUNTED
- The interim fix was installed with a mount installation
operation, and successfully completed the last installation or mount operation. A state of
MOUNTEDdoes not mean all interim fixes are currently mounted. For example, the interim fixes might have been manually unmounted. This state represents the emgr command's previous actions and determination of the mount status. To verify the interim fix details, including mount status, run a check operation on the given interim fix or interim fixes. - U=UNMOUNTED
- The interim fix was installed with a mount installation
operation and one or more interim fix files were unmounted
in a previous emgr command operation. The state of
UNMOUNTEDdoes not mean that all interim fixes are currently unmounted. For example, the interim fixes might have been manually mounted or partially mounted. This state represents the emgr command's previous actions and determination of the mount status. To verify the interim fix details, including mount status, run a check operation on the given interim fix or interim fixes. - B=BROKEN
- An unrecoverable error occurred during an installation or removal operation. The status of the interim fix is unreliable. You can attempt to remove this interim fix and reinstall it from the interim fix package.
- I=INSTALLING
- The interim fix is
in the process of installing. Normally, this state occurs only for
a brief time during interim fix installation.
However, if an interim fix installation
is suddenly interrupted (such as in a sudden power loss or a system
crash), and the emgr command is unable to clean
up the failed installation, an interim fix might be left
in the
INSTALLINGstate. You can attempt to remove this interim fix and reinstall it from the interim fix package. - Q=REBOOT REQUIRED
- The interim fix was
installed successfully and requires a reboot to fully integrate into
the target system. After you reboot the target system, emgr changes
the interim fix state
to
STABLE.Note:- This feature is not supported in the original release of interim fix management. You should update to the latest level of interim fix management to enable this feature. To update interim fix management, update bos.rte.install to the latest level.
- emgr is called by init with the
-B bootup flag during system start. emgr examines the
state data for all interim fixes and changes the interim fix states as necessary. The /etc/inittab entry
rcemgris created the first time emgr installs an interim fix file.rcemgris set to not block or respawn. Allrcemgractivities and output are logged to the emgr log in /var/adm/ras/emgr.log. Do not directly execute emgr with the -B flag.
- R=REMOVING
- The interim fix is
in the process of being removed. Normally, this state occurs only
for a brief time during interim fix removal. However,
if an interim fix installation
is suddenly interrupted (such as in a sudden power loss or a system
crash), and the emgr command is unable to clean
up the failed installation, an interim fix might be left
in the
REMOVINGstate. You can attempt to remove this interim fix and reinstall it from the interim fix package. - T = TESTED
- Specifies that the interim fix was tested. Reflects the value of the epkg command -T flag that may be used during package creation.
- P = PATCHED
- Concurrent update has been patched directly in memory. Corresponding binaries on disk have not been modified.
- N = NOT PATCHED
- Concurrent update has been "updated by" a follow-on concurrent
update, making the patch inactive.
State is also set during reboot to change the state of in memory only concurrent updates that were in the PATCHED state.
- SP = STABLE + PATCHED
- Concurrent update has been patched in memory and the corresponding on-disk binaries have been replaced. The fix will now persist on the system across reboots.
- SN = STABLE + NOT PATCHED
- A concurrent update in the STABLE + PATCHED state will be moved
to this state when it is "updated by" a follow-on concurrent update,
making the patch inactive.
State may also be set if an interim fix containing a concurrent update in the NOT PATCHED state is committed to disk.
- QP = BOOT IMAGE MODIFIED + PATCHED
- Same as Stable + Patched except that, in replacing on-disk binaries, a file belonging in the boot image was modified and bosboot was invoked.
- QN = BOOT IMAGE MODIFIED + NOT PATCHED
- A concurrent update in the BOOT IMAGE MODIFIED + PATCHED state
will be moved to this state when it is "updated by" a follow-on concurrent
update, making the patch inactive.
State may also be set if an interim fix containing a concurrent update in the NOT PATCHED state is committed to disk.
- RQ = REMOVING + REBOOT REQUIRED
- When an interim fix that was committed to disk has been removed, the system must be rebooted to remove all patched code from memory. The interim fix will be removed from the Interim Fix database by the rc_emgr function called by init at boot time.
