Is LLDP supported on a Dell Unity array?

This article discusses whether Unity is susceptible to CVE-2026-20833.

When a system drive fails in a traditional pool, a hotspare is used to copy customer data luns. Once the system drive is replaced, the system drive does not become available as a hotspare. This could lead to a hotspare rule failure as there is one less hotspare available.

When we cancel a pool expansion job using UEMCLI, the storage reports that the action was completed successfully although the operation continues in the background. This behavior is corrected in OE 5.1.

Under certain out-of-space conditions, an upgrade to 5.1 may trigger file system offline or rolling SP reboots.

When performing a Pre-Upgrade Health Check (PUHC) on Unity OE 5.1 or later code, it may report an error: dm::check_if_user_root_fs_has_enough_space_1

After upgrading Unity some administrative issues regarding the VMFS datastore can be noticed. 1. Failure or partial failure adding or removing datastore access to ESXi hosts through Unisphere. 2. From vCenter, it is not possible to see datastore name changes made from Unisphere.

Unity arrays running 5.3.0.0.5.120 code with SupportAssist enabled may experience an SP panic after being up for approximately 2 months with a two SCG configuration or after approximately 4 months with a single SCG configuration, or direct connect.

When uploading text files to Unity's FTP server, file formatting may become invalid due to the difference between Windows and Unix/Linux end-of-line (EOL) characters. Windows uses two characters, CR+LF while Unix/Linux only uses LF. By default, Unity's FTP server uses ASCII transfer mode and since Unity uses a Unix/Linux base, all EOL characters are converted to LF. This makes files appear to be broken when read from a Windows client. To avoid this behavior, files should be uploaded using bin transfer mode. This makes sure the file is transferred "as is" with no changes. This may also be helpful when transferring image, audio and video files as they also require binary mode to avoid corruption.

It has been observed that some Solid-State Drive (SSD) models may have their End-of-Life (EOL) flag set after accumulating a total power-on time of approximately 6.8 years or more. This flag indicates that the drive has reached the end of its expected lifespan and may no longer be supported or guaranteed to function reliably.

SPCv controller can hang in PHY_STOP (Physical Layer Stop) command with IOs. This can cause the SPCv controller to crash causing SP panic.

Unisphere GUI and CLI via SSH are no longer accessible after attempting to change DNS settings. Restarting management services does not resolve the issue. It was also determined that ECOM does not start on either SP or stay running for more than 10 minutes.

Red Had Enterprise Linux client was unable to mount Unity NAS Server NFS Share. Receiving error NFS4ERR_MINOR_VERS_MISMATCH.

Some IDs such as Fake, nobody, c4, log, nogroup, admin, service, ECOM etc were found while scanning the Unity Array.

A system is either having its Management IP address configured during deployment or having the management IP address subnet changed. When a gateway is chosen, if the Subnet ID is used the Management IP configuration fails. This can occur either within Unisphere or at the command line. An error is seen about a failure to change the management IP configuration in Unisphere and also at the command line. Both Unisphere and the command line will be unable to be logged into. Access from ipmitool on either SP must be used to continue and resolve the issue.
