HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

• Causes LSM tol issue an error if a nonroot user tries to run the volencap command.
• Decreases CLSM boot times in large cluster configurations.
• Fixes problems in vol_new_disk ioctl when errors are encountered when loading a disk in
the kernel.
• Fixes a problem with the disk group loglen getting set to 0 when adding a disk to a non-rootdg
disk group.
• Fixes an LSM problem in which device failures may not be handled properly in a cluster.
This is with respect to devices discovered from a previous configuration. The result could
be a diskgroup deport.
• Fixes a vold threads problem in which LSM devices may be incorrectly recorded as disk
clones where LSM starts up,
• Provides a new LSM EVM event, which is posted when LSM is processing clusterwide plex
detaches.
• Modifies LSM to ensure that AdvFS volume links are not required to be named the same as
the device they point to.
• Corrects a problem in which the dsfmgr command does not notify LSM of certain disk
changes With this fix, the procure for replacing a failed boot disk under LSM control should
work as described in Section 6.4.6 of the Logical Storage Manager manual without generating
the error message “lsm:voldisk: ERROR: Device dskxf: define failed.”
• Corrects a condition that causes the incorrect use of the volmigrate and volunmigrate
commands to return success instead of failure.
• Fix a problem in voldisk moddb that can cause a disk group to become unusable.
• Enhances CLSM performance during boot and disk scanning.
• Fixes a problem in voldisk moddb that can cause a disk group to become unusable.
• Fixes the voldiskadm utility to correctly remove a disk for replacement.
• Fixes a problem whereby LSM mirrored volumes are erroneously left in the SYNC state
after a cluster member failure and simultaneous underlying disk storage failure.
• Fixes an error in dissociating swapvol/rootvol plexes.
• Corrects incorrect error messages generated by the voldctl command. With this fix, if voldctl
disable fails, the error message returned will be “disable failed” and if voldctl license fails,
the error message will be “license check failed.”
• Corrects a problem to ensure the correct calculation of subdisk offsets in a plex when
associating subdisks to a plex using the volsd command.
• Corrects a problem with non-rootdg disk groups disappearing.
Patch 27052.00
OSFLSMBIN540
• Prevents the following panics on systems using LSM or CLSM with low free memory:
mcs_lock: lock already owned by cpu
mcs_unlock: current lock not found
• Suppresses the following erroneous console warning message that may be provided when
cluster root is under LSM control.
WARNING: cluster root devices are on private buses!
LSM does not support such configurations.
• Corrects a highly contentious spin lock in the LSM kernel that occurs when running a high
number of I/O operations to an LSM volume.
• Corrects a problem to allow CLSM ioctls to return EINVAL when not in a cluster.
• Prevents the dereferencing of a null pointer in volkiostart() when a DRL object has failed
and no mirrors belong to the object.
