I recently created a pair of 25TB LUs for use in my VMware environment to test out Veeam (and using that space for my repo - yes, yes, backups should not reside in the same storage, but they will be exported to tape).
So while trying to create a 16TB drive in the vSphere fat client, I got the value out of range error ( http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2054952). OKed the error, and task seemed to run anyways, but at some point my whole SAN crashed during the creation of the drive. As this was during business hours, I did not have time to wait on the dump, but I was able to reproduce it later trying to create a 10TB drive (again from the fat vSphere client, not web client) and capture the dump (which takes 40 minutes.. grr). Just an quick note on the environment: the VMware hosts are connected to the head unit via IB and SRP. The largest LUs I had previously created for VMware were 5TB in size, and largest drive created was 2TB. fmdump info: TIME UUID SUNW-MSG-ID Mar 20 2015 19:35:26.819716000 31ced65f-dca2-ee58-c882-a6daa6b94208 SUNOS-8000-KL nvlist version: 0 version = 0x0 class = list.suspect uuid = 31ced65f-dca2-ee58-c882-a6daa6b94208 code = SUNOS-8000-KL diag-time = 1426894526 787544 de = fmd:///module/software-diagnosis fault-list-sz = 0x1 fault-list = (array of embedded nvlists) (start fault-list[0]) nvlist version: 0 version = 0x0 class = defect.sunos.kernel.panic certainty = 0x64 asru = sw:///:path=/var/crash/unknown/.31ced65f-dca2-ee58-c882-a6daa6b94208 resource = sw:///:path=/var/crash/unknown/.31ced65f-dca2-ee58-c882-a6daa6b94208 savecore-succcess = 1 dump-dir = /var/crash/unknown dump-files = vmdump.0 os-instance-uuid = 31ced65f-dca2-ee58-c882-a6daa6b94208 panicstr = kernel heap corruption detected panicstack = fffffffffba49114 () | genunix:kmem_slab_free+c1 () | genunix:kmem_magazine_destroy+6e () | genunix:kmem_cache_magazine_purge+f0 () | genunix:kmem_cache_magazine_resize+40 () | genunix:taskq_thread+2d0 () | unix:thread_start+8 () | crashtime = 1426891707 panic-time = Fri Mar 20 18:48:27 2015 EDT (end fault-list[0]) fault-status = 0x1 severity = Major __ttl = 0x1 __tod = 0x550caebe 0x30dbdfa0 Crash file: https://drive.google.com/open?id=0B7mCJnZUzJPKOXl1S3IwYXh4NTg&authuser=0 I couldn't find any interesting comparative posts/reports. Would some kind soul care to look at the dump and see what is happening here? (And is this the right spot for a kernel panic report, or is it better to go to the illumos list?)
