• Fixes incorrect CFS token structure warnings.
• Prevents file inconsistency due to a race between lookup and remove.
• Provides a new cluster-specific link aggregation distribution algorithm when using LAG in
a LAN cluster.
• Fixes a simple lock timeout panic issue in kch and a possible hang at boot time
• Prevents an AIO DirectIO to return invalid data while reading a fragged file.
• Fixes a cluster hang issue during cluster boot-up, when local disk open operations fail while
disklabel is in progress.
• Fixes an error in the DRD subsystem wherein un-initialized disk attributes can cause a
system panic.
• Fixes KMF in rdg_get_completion() routine.
• Fixes a problem in which a cluster alias subsystem tries to free the mbuf that is already freed
by ICS subsystem.
• Corrects reference counting issues within the DRD subsystem that can prevent the deletion
of hwids.
• Adds a new option, custom_gated, to cluamgr and aliasd.
• Fixes a deadlock that can happen during failover of global root and var file systems when
vfast is enabled on them.
• Fixes resource leaks seen after a locked device file is revoked.
• Fixes system panics seen on relocating file systems with locked revoked devices.
• Fixes a problem with CAA placement policy when host names in "HOSTING MEMBERS"
are in uppercase letters.
• Corrects a problem in which CAA is incorrectly showing the status of network resources
on a halted member.
• Fixes a problem in cfs block reservation code where cfs attempted to release a lock more
than once.
• Introduces a code tracing capability of the aliasd and aliasd_niff daemons to improve
troubleshooting.
• Prevents a race that can occur during the planned relocation of a file system.
• Improves the reliability of the DRD subsystem when faced with tape devices and tape device
failures.
• Introduces a mechanism to improve reliability for synchronizing cluster alias ID sets among
cluster members.
• Fixes the cause of the following CNX panic in cluster reconfiguration:
cnx_change_cluster_tx_state: illegal transaction state
• Fixes an ICS panic issue that occurs early in the boot process.
• Fixes a problem that causes the cluster alias manager SUITlet to falsely interpret any cluster
alias with virtual={t|f} configured as a virtual alias regardless of its actual setting.
• Corrects problems in which SysMan drdmgr dumps tcl stack when a user tries to manage
devices or file systems of a cluster node that is down.
• Corrects an issue to allow the Device Request Dispatcher, DRD, to retry to get disk attributes
when EINPROGRESS is returned from the disk driver.
• Address issues with “address already in use” messages from klogin and kshell.
• Corrects a potential security vulnerability in CAA.
• Fixes a kernel memory fault.
• Corrects a problem in which the MC-API call imc_ckerrcnt_mr()incorrectly returns an error

• Preserves the error code from an asynchronous write error on a CFS client and returns the
error from the close() system call.
