Diagnostics and Troubleshooting Reference Manual – Virtual SAN On-disk format upgrade pre-check: vsan.disks_stats The vsan.disks_stats in version 6.0 will also display the version number of the on-disk format displayed in the right hand column (e.g. v1 or v2). Here is a cluster upgraded to vSphere version 6.0 but still using the original on-disk format (v1). Note the (v1) in the Status Health column on the right hand side: vsan.disks_stats /localhost/ie-datacenter-04/computers/ie-vsan/ 2014-11-10 15:08:46 +0000: Fetching VSAN disk info from cs-ie-h04.ie.local (may take a moment) ... 2014-11-10 15:08:46 +0000: Fetching VSAN disk info from cs-ie-h01.ie.local (may take a moment) ... 2014-11-10 15:08:46 +0000: Fetching VSAN disk info from cs-ie-h02.ie.local (may take a moment) ... 2014-11-10 15:08:46 +0000: Fetching VSAN disk info from cs-ie-h03.ie.local (may take a moment) ... 2014-11-10 15:08:48 +0000: Done fetching VSAN disk infos +--------------------------------------+--------------------+-------+------+-----------+------+----------+---------+ | | | | Num | Capacity | | | Status | | DisplayName | Host | isSSD | Comp | Total | Used | Reserved | Health | +--------------------------------------+--------------------+-------+------+-----------+------+----------+---------+ | naa.600508b1001c61cedd42b0c3fbf55132 | cs-ie-h01.ie.local | SSD | 0 | 130.39 GB | 0 % | 0 % | OK (v1) | | naa.600508b1001c2ee9a6446e708105054b | cs-ie-h01.ie.local | MD | 0 | 136.50 GB | 1 % | 0 % | OK (v1) | | naa.600508b1001c16be6e256767284eaf88 | cs-ie-h01.ie.local | MD | 0 | 136.50 GB | 1 % | 0 % | OK (v1) | | naa.600508b1001ccd5d506e7ed19c40a64c | cs-ie-h01.ie.local | MD | 0 | 136.50 GB | 1 % | 0 % | OK (v1) | | naa.600508b1001c64816271482a56a48c3c | cs-ie-h01.ie.local | MD | 0 | 136.50 GB | 1 % | 0 % | OK (v1) | | naa.600508b1001c388c92e817e43fcd5237 | cs-ie-h01.ie.local | MD | 0 | 136.50 GB | 1 % | 0 % | OK (v1) | | naa.600508b1001c3ea7838c0436dbe6d7a2 | cs-ie-h01.ie.local | MD | 0 | 136.50 GB | 1 % | 0 % | OK (v1) | | naa.600508b1001c79748e8465571b6f4a46 | cs-ie-h01.ie.local | MD | 0 | 136.50 GB | 1 % | 0 % | OK (v1) | +--------------------------------------+--------------------+-------+------+-----------+------+----------+---------+ | naa.600508b1001c577e11dd042e142a583f | cs-ie-h02.ie.local | SSD | 0 | 130.39 GB | 0 % | 0 % | OK (v1) | | naa.600508b1001ca36381622ca880f3aacd | cs-ie-h02.ie.local | MD | 25 | 136.50 GB | 10 % | 9 % | OK (v1) | | naa.600508b1001cb2234d6ff4f7b1144f59 | cs-ie-h02.ie.local | MD | 18 | 136.50 GB | 18 % | 17 % | OK (v1) | | naa.600508b1001c19335174d82278dee603 | cs-ie-h02.ie.local | MD | 1 | 136.50 GB | 92 % | 92 % | OK (v1) | | naa.600508b1001c0cc0ba2a3866cf8e28be | cs-ie-h02.ie.local | MD | 21 | 136.50 GB | 26 % | 25 % | OK (v1) | | naa.600508b1001c10548f5105fc60246b4a | cs-ie-h02.ie.local | MD | 14 | 136.50 GB | 10 % | 10 % | OK (v1) | | naa.600508b1001c07d525259e83da9541bf | cs-ie-h02.ie.local | MD | 24 | 136.50 GB | 92 % | 92 % | OK (v1) | +--------------------------------------+--------------------+-------+------+-----------+------+----------+---------+ | naa.600508b1001c9c8b5f6f0d7a2be44433 | cs-ie-h03.ie.local | SSD | 0 | 130.39 GB | 0 % | 0 % | OK (v1) | | naa.600508b1001ceefc4213ceb9b51c4be4 | cs-ie-h03.ie.local | MD | 52 | 136.50 GB | 8 % | 7 % | OK (v1) | | naa.600508b1001cd259ab7ef213c87eaad7 | cs-ie-h03.ie.local | MD | 1 | 136.50 GB | 92 % | 92 % | OK (v1) | | naa.600508b1001c1a7f310269ccd51a4e83 | cs-ie-h03.ie.local | MD | 2 | 136.50 GB | 92 % | 92 % | OK (v1) | | naa.600508b1001c9b93053e6dc3ea9bf3ef | cs-ie-h03.ie.local | MD | 23 | 136.50 GB | 31 % | 13 % | OK (v1) | | naa.600508b1001cb11f3292fe743a0fd2e7 | cs-ie-h03.ie.local | MD | 13 | 136.50 GB | 7 % | 7 % | OK (v1) | | naa.600508b1001c2b7a3d39534ac6beb92d | cs-ie-h03.ie.local | MD | 14 | 136.50 GB | 9 % | 8 % | OK (v1) | +--------------------------------------+--------------------+-------+------+-----------+------+----------+---------+ | naa.600508b1001c40e393b73af79eacdcde | cs-ie-h04.ie.local | SSD | 0 | 130.39 GB | 0 % | 0 % | OK (v1) | | naa.600508b1001c51f3a696fe0bbbcb5096 | cs-ie-h04.ie.local | MD | 9 | 136.50 GB | 4 % | 4 % | OK (v1) | | naa.600508b1001c4b820b4d80f9f8acfa95 | cs-ie-h04.ie.local | MD | 9 | 136.50 GB | 5 % | 4 % | OK (v1) | | naa.600508b1001cadff5d80ba7665b8f09a | cs-ie-h04.ie.local | MD | 53 | 136.50 GB | 5 % | 5 % | OK (v1) | | naa.600508b1001c846c000c3d9114ed71b3 | cs-ie-h04.ie.local | MD | 10 | 136.50 GB | 5 % | 5 % | OK (v1) | | naa.600508b1001c258181f0a088f6e40dab | cs-ie-h04.ie.local | MD | 12 | 136.50 GB | 13 % | 12 % | OK (v1) | | naa.600508b1001c4d41121b41182fa83be4 | cs-ie-h04.ie.local | MD | 10 | 136.50 GB | 5 % | 4 % | OK (v1) | +--------------------------------------+--------------------+-------+------+-----------+------+----------+---------+ If everything is healthy, there is a new Virtual SAN 6.0 command, vsan.v2_ondisk_upgrade, to upgrade the on-disk format.

Diagnostics and Troubleshooting Reference Manual – Virtual SAN On-disk format upgrade: vsan.v2_ondisk_upgrade This command will rotate through each of the hosts in the Virtual SAN cluster (rolling upgrade), doing a number of verification checks on the state of the host and cluster before evacuating components from each of the disk groups and rebuilding them elsewhere in the cluster. It then upgrades the on-disk format from v1 to v2. Even though the command is an RVC command, you will be able to monitor the tasks associated with the on-disk upgrade via the vSphere web client UI. In particular, the task Remove disks from use by Virtual SAN followed by Add disks to Virtual SAN will be seen. Using the Monitor > Virtual SAN > Resyncing components view, you can also see how much data is left to resync, and an ETA to compliance: Note that there is no need to manually place the host in maintenance mode or evacuate any data. The RVC script will handle all of these tasks. V M W A R E S T O R A G E B U D O C U M E N T A T I O N / 1 6 9
