Long time since we had RDMs, I think back then we had to do them at the Windows VM level, present it new disks from the new array and create mirrors in Windows then remove the old disks and LUNs. If it's an alletra 9k you might be able to use the 3PAR migration tools, can't remember if they support ...

We've not used the HPE one for Nimble servers, just native. Check the docs on infosight for what settings to use (I think the Nimble docs mentioned what to set but I've not seen the Alletra 5k docs). They'll probably still recommend using the HPE one, apart from when they find bugs and ask you to sw...

Thank you for the info! I can get on with my migration scripting now. I even found a HPE Alletra 9000 'tutorial' video on CPGs, although it went on about them controlling RAID type and set sizes when it got to the demo part they just did a "createcpg <name>" and "removecpg <name>"...

Comparing 3PAR CLI commands to Alletra 9000 CLI commands (via the docs) I find most to be the same with a couple of parameter changes. However the createcpg command seems to missing both the RAID type and RAID set size parameters, I presume that everything is RAID6 on Alletra so no option but how do...

Although don't forget that (if required) you need to tune both the user space and the snap space, two different tasks (if no snap space in use you can often get away with just editing the VV properties and changing the CPG there).

I think I started off with all nodes originally, with 2 fabrics that gave 8 active paths. When peer persistence came along there was some mention somewhere of the max paths per host being 8 and so I changed to using node pairs (4 active paths and 4 standby paths). I split my clusters up so they were...

The HPE SPOCK site has a doc called 3par_upgrade_recommend.pdf, the current version lists the following mandatory pre upgrade patches; P32, P34, P40, P45, P51, P76, P90, P113 & P127. I think as long as you have those you should be okay, add the latest update tools U042 just to be sure. P111 is l...

Yeah I missed the announcement originally, still have one box on 3.2.2 which I'm not looking forward to upgrading to 3.3.1 solo. Luckily for me everything else was on 3.3.1 MU5 so I've only had the basic patch installs to deal with (had been doing them on some 8400s for a while to save time as the s...

By default all disk space becomes a single pool of space, so when you add new disks they will just expand the pool, allowing growth of any VV. There are a few things to take into consideration though, if you want to expand a VV by 1TB don't just buy 1TB of new raw disk. You have to take into account...

Each pair of nodes would have a separate set of trays/disks connected to it. So if the system lost 2 disks they might be in opposite node pairs, so the the equivalent of only a single disk failure on a two node system. Of course you still might be unlucky and the 2 disks fail behind a single node pa...
