You must allow these signed kernel extensions to be used (Security & Privacy System Preferences Pane) for the SNS software you've installed. MacOS High Sierra introduced a new security feature that requires user approval before loading new third-party kernel extensions-this remains in Catalina. Important note regarding all SNS software in High Sierra and later We recommend avoiding macOS Catalina until Apple has issued a fix. Though the issue is not widespread and does not affect all Catalina users, it can be very disruptive. (There are reports on the internet that the problem can present similarly with the NFS protocol, but we have not confirmed this.) The problem is not specific to EVO, nor does it appear to be limited to a particular NIC/chipset. We will continue testing and monitoring before making further announcements.įebruary 4, 2020: We have confirmed a networking issue in macOS Catalina, which, under certain loads can cause an SMB share to disconnect. We have deployed modifications to affected customers who have elected to stay with Catalina, and reports are positive so far. The following product statements cover whether or not something major is affected simply by the process of upgrading to Catalina.įebruary 10, 2020: We have identified a potential solution for the February 4 issue below. (But then, if you're reading this statement you probably already know this, and you know that a backup is also recommended!!) non-SNS) software and hardware products are compatible with this new OS from Apple. Prior to upgrading, you should also verify that your other (i.e. Since the original question was about (client) iSCSI Initiator rather than file sharing (MP) I did not include information about the other SNS products including Xtarget which is an iSCSI server application).We are providing these updates to our customers who would like to know the status of SNS products before upgrading a workstation to macOS 10.15 Catalina. Of course, if multiple connections are enabled, then the iSCSI user(s) are responsible for whatever happens to the Target data. One interesting note about Synology DiskStation level NAS/SAN servers (at least for the ds216 series) is that their configuration has an expliciit "allow/disallow multiple connections" for each defined Target so multiple connections to the same available Target can be managed at the iSCSI server level. I mentioned that when using globalSAN that it automatically discovers ALL available iSCSI Targets and presents them in its Preferences interface - and - that users need to manually select which one to use - and - be very careful to choose the correct one. Whilst I cannot find iSANmp on the SNS web site, a 3rd party offering for it listed a $199 price - way more than for globalSAN ($89). SANmp and Xsan are FiberChannel based applications whereas globalSAN/iSANmp are ethernet based. Read and understand all of the requirements and implications before using. This process requires booting from Recovery OS. One from GitHub, "iscsi-osx/iSCSIinitiator", (free) requires disabling System Integrity Protection as their application is not (Apple) signed. There are some others which if you look at Internet postings are somewhat questionable as to use/currenency.
